Display device

Abstract

A display device is provided that inhibits color mixture between adjacent subpixels and allows for obtaining a high-quality image. The display device includes a display area on which a light-blocking metal layer, a black matrix, and a plurality of subpixels are arranged, wherein the plurality of subpixels are arranged adjacent to one another via a black matrix as seen vertically from above, the black matrix and the light-blocking metal layer are arranged to overlap each other as seen vertically from above, and the light-blocking metal layer 130 is arranged on the bank of an organic flattened film.

What is claimed is: 
     
         1 . A liquid crystal display device comprising:
 a first substrate including a thin-film transistor, a scanning signal line, a pixel electrode and a video signal line;   a second substrate including a black matrix; and   a liquid crystal layer disposed between the first substrate and the second substrate,   wherein the black matrix and the video signal line are arranged to overlap each other in view from vertically above,   the first substrate has an organic planarization layer disposed between the liquid crystal layer and the video signal line,   the organic planarization layer disposed above the video signal line has a convex shape along the video signal line,   the thickness of the liquid crystal layer disposed above the video signal line is thinner than the thickness of the liquid crystal layer above the pixel electrode.   
     
     
         2 . The display device according to  claim 1 , wherein
 a light-shielding metal layer is placed above top portion of the convex shape of the organic planarization layer,   the light-shielding metal layer is closer to the second substrate than the pixel electrode.   
     
     
         3 . The display device according to  claim 2 , wherein
 an alignment film is arranged above top of the light-shielding metal layer.   
     
     
         4 . The display device according to  claim 2 , wherein
 a common electrode is disposed between the pixel electrode and the organic planarization layer.   
     
     
         5 . The display device according to  claim 4 , wherein
 the common electrode is also formed above the top portion of the convex shape of the organic planarization layer.   
     
     
         6 . The display device according to  claim 4 , wherein
 the common electrode has an opening portion in the area of the convex shape of the organic planarization layer.   
     
     
         7 . The display device according to  claim 6 , wherein
 an edge portion of the opening of the common electrode is disposed on the side wall portions of the convex shape of the organic planarization layer.
