Reflective-transmissive type liquid crystal display device

Abstract

A reflective-transmissive liquid crystal display (LCD) device with an improved display quality is achieved by forming a reflective area and a transmissive area having a cell gap greater than greater than that of the reflective area. A liquid crystal layer is disposed in a liquid crystal cell between the first and second substrates. The liquid crystal molecules are normally aligned at an angle equal to greater than about 45° with respect to a line parallel to the first substrate. The LCD device operates in a normally black mode.

1 . A method for manufacturing a liquid crystal display (LCD) device, the method comprising steps of:
 forming a gate line on a substrate;   forming a data line intersecting the gate line at a first corner of a pixel region;   forming a passivation layer covering the gate line and the data line; and   forming an opening in the passivation layer to form a transmissive region in the pixel region, the opening formed closer to the first corner than other corners of the pixel region.   
   
   
       2 . The method of  claim 1 , wherein a direction from a center of the pixel region to the first corner substantially coincides a rubbing direction of the pixel region. 
   
   
       3 . The method of  claim 1 , further comprising a step of forming a light barrier pattern overlapping a side of the opening. 
   
   
       4 . The method of  claim 3 , wherein the step of forming the light barrier pattern comprises a step of forming a first light barrier pattern overlapping a first side of the opening. 
   
   
       5 . The method of  claim 4 , wherein the gate line and the first light barrier are formed simultaneously. 
   
   
       6 . The method of  claim 4 , wherein the step of forming the light barrier pattern further comprises a step of forming a second light barrier pattern overlapping a second side of the opening. 
   
   
       7 . The method of  claim 6 , wherein the data line and the second light barrier pattern are formed simultaneously. 
   
   
       8 . The method of  claim 6 , further comprising a step of forming a reflective plate on a reflective region of the pixel region. 
   
   
       9 . The method of  claim 8 , wherein the reflective plate is extended to overlap at least a side of the opening. 
   
   
       10 . The method of  claim 9 , wherein the reflective plate is extended to overlap all sides of the opening.
