Display device and manufacturing method thereof

Abstract

A display device may include a first subpixel electrode; a first roof layer; a first liquid crystal layer disposed between the first subpixel electrode and the first roof layer; and a first support member overlapping a first end portion of the first roof layer in a first direction. The display device may further include a second subpixel electrode immediately neighboring the first subpixel electrode; a second roof layer; a second liquid crystal layer disposed between the second subpixel electrode and the second roof layer; and a second support member overlapping a first end portion of the second roof layer in the first direction. The first end portion of the first roof layer and the first end portion of the second roof layer may be disposed between a second end portion of the first roof layer and a second end portion of the second roof layer.

What is claimed is: 
     
         1 . A method for manufacturing a display device, the method comprising:
 forming a first subpixel electrode and a second subpixel electrode, the second subpixel electrode immediately neighboring the first subpixel electrode without any subpixel electrode being disposed between the first subpixel electrode and the second subpixel electrode;   forming a first roof layer and a second roof layer;   forming a first support member and a second support member, wherein the first support member overlaps a first end portion of the first roof layer in a first direction, wherein the second support member overlaps a first end portion of the second roof layer in the first direction, and wherein the first end portion of the first roof layer and the first end portion of the second roof layer are disposed between a second end portion of the first roof layer and a second end portion of the second roof layer; and   forming a first cavity and a second cavity, wherein a portion of the first cavity is positioned between the first subpixel electrode and the first roof layer, and wherein a first portion of the second cavity is positioned between the second subpixel electrode and the second roof layer.   
     
     
         2 . The method of  claim 1 ,
 wherein the second end portion of the first roof layer does not overlap, in the first direction, any support member that is analogous to the first support member or the second support member, and   wherein the second end portion of the second roof layer does not overlap, in the first direction, any support member that is analogous to the first support member or the second support member.   
     
     
         3 . The method of  claim 1 , further comprising:
 forming a third subpixel electrode, which immediately neighbors the second subpixel electrode without any subpixel electrode being disposed between the second subpixel electrode and the third subpixel electrode,   wherein the second subpixel electrode is disposed between the first subpixel electrode and the third subpixel electrode,   wherein the second roof layer overlaps both the second subpixel electrode and the third subpixel electrode,   wherein a second portion of the second cavity is positioned between the third subpixel electrode and the second roof layer,   wherein a center portion of the second roof layer is disposed between the first end portion of the second roof layer and the second end portion of the second roof layer, and   wherein the center portion of the second roof layer does not overlap, in the first direction, any support member that is analogous to the first support member or the second support member.   
     
     
         4 . The method of  claim 3 , further comprising:
 forming a fourth subpixel electrode, which immediately neighbors the third subpixel electrode without any subpixel electrode being disposed between the third subpixel electrode and the fourth subpixel electrode;   forming a third roof layer, which overlaps the fourth subpixel electrode in the first direction; and   forming a third cavity, wherein a portion of the third cavity is positioned between the fourth subpixel electrode and the third roof layer,   wherein the third subpixel electrode is disposed between the second subpixel electrode and the fourth subpixel electrode,   wherein the second end portion of the second roof layer and a first end portion of the third roof layer are disposed between the first end portion of the second roof layer and a second end portion of the third roof layer, and   wherein the first end portion of the third roof layer does not overlap, in the first direction, any support member that is analogous to the first support member or the second support member.   
     
     
         5 . The method of  claim 4 , further comprising:
 forming a third support member, which overlaps the second end portion of the third roof layer in the first direction.   
     
     
         6 . The method of  claim 4 , further comprising:
 providing a liquid crystal material through a gap between the second roof layer and the third roof layer to the second cavity and the third cavity; and   preventing providing any liquid crystal material through a gap between the first roof layer and the second roof layer.   
     
     
         7 . The method of  claim 4 , further comprising:
 providing an alignment layer material through a gap between the second roof layer and the third roof layer to the second cavity and the third cavity; and   preventing providing any alignment layer material through a gap between the first roof layer and the second roof layer.   
     
     
         8 . The method of  claim 1 , further comprising:
 forming a step member between the first support member and the first roof layer, wherein a width of the step member in a second direction is larger than a width of the first support member in the second direction.   
     
     
         9 . The method of  claim 1 , further comprising:
 forming the first support member, the first roof layer, and a step member between the first support member and the first roof layer using a same material.   
     
     
         10 . The method of  claim 1 , further comprising:
 forming an insulating layer between the first support member and the first subpixel electrode,   wherein the first support member overlaps the first subpixel electrode in the first direction.   
     
     
         11 . The method of  claim 1 , wherein the first support member does not overlap the first subpixel electrode in the first direction.
