Display device and manufacturing method thereof

Abstract

A display device includes a substrate, and a group pixel on the substrate, the group pixel comprising at least two pixels that represent the same color, wherein in the group pixel, a distance between the pixels is smaller than a distance between adjacent pixels of different group pixels.

1 - 4 . (canceled) 
     
     
         5 . The display device of  claim 10 , further comprised of: the group pixel displaying any one of red, green, and blue, the blue group pixel being disposed diagonally, and the red and green group pixels being disposed diagonally to each other. 
     
     
         6 . The display device of  claim 10 , further comprised of: the group pixel displaying any one of red, green, and blue, the red group pixel being disposed diagonally, and the blue and green group pixels being disposed diagonally to each other. 
     
     
         7 . The display device of  claim 10 , further comprised of: the group pixel displaying any one of red, green, and blue, the green group pixel being disposed diagonally, and the red and blue group pixels being disposed diagonally to each other. 
     
     
         8 . The display device of  claim 10 , wherein the pixel comprises:
 a first electrode disposed on the substrate, the first electrode comprising a plurality of first sub-electrodes;   a pixel defining layer disposed between the first sub-electrodes and on an end portion of the first electrode;   an emission layer on the first electrode; and   a second electrode on the emission layer.   
     
     
         9 . The display device of  claim 8 , wherein the emission layer is applied on the pixel defining layer in the same group pixel as the pixel defining layer. 
     
     
         10 . A method for manufacturing a display device, the method comprising:
 preparing a substrate;   forming a first electrode on the substrate;   forming an emission layer on the first electrode; and   forming a second electrode on the substrate on which the emission layer is formed,   wherein the forming of an emission layer uses a mask having an opening corresponding to a group pixel in which a plurality of pixels representing the same color are disposed to be rectangular.   
     
     
         11 . The method of  claim 10 , wherein the opening of the mask has the same area as each group pixel. 
     
     
         12 . The method of  claim 10 , wherein the opening of the mask has a larger area than each group pixel. 
     
     
         13 . The method of  claim 10 , wherein the group pixel comprises four pixels that are formed to be rectangular. 
     
     
         14 . The method of  claim 13 , wherein the group pixel comprises four pixels of which two pixels each are disposed horizontally and vertically. 
     
     
         15 . The method of  claim 10 , wherein the group pixel comprises two pixels disposed horizontally or vertically. 
     
     
         16 . The display device of  claim 10 , further comprised of the distance between the pixels in the group pixel has a value smaller that a least distance that prevents a mixture of different colors between pixels. 
     
     
         17 . The display device of  claim 10 , further comprised of the least distance between the neighboring pixels in the different group pixels is not smaller than a least distance that prevents a mixture of different colors between pixels. 
     
     
         18 . The display device of  claim 10 , further comprised of a least distance between the neighboring pixels in the different group pixels is about 22 μm. 
     
     
         19 . The display device of  claim 10 , each of the pixels increasing in size when the distance between the pixels in the group pixel is reduced. 
     
     
         20 . The method of  claim 10 , the opening of the mask is not substantially reduced when resolution increases and pixel area decreases.
