a light blocking member disposed around a display area of the substrate, wherein a corner of the light blocking member has a rounded edge; a plurality of pixels disposed on the substrate; and a pixel electrode disposed in each of the plurality of pixels, wherein the pixel electrode has a horizontal stem, a vertical stem, and a plurality of fine branches, wherein the plurality of pixels includes a first pixel at least partially overlapping the light blocking member and a second pixel adjacent to the first pixel and not overlapping the light blocking member, and wherein a shape of a fine branch disposed in the first pixel is different from a shape of a fine branch disposed in the second pixel. ## Claims ### Claim 1 A display device comprising: a substrate; a light blocking member disposed around a display area of the substrate, wherein a corner of the light blocking member has a rounded edge; and a plurality of pixels disposed on the substrate, wherein the plurality of pixels comprises: a first subpixel directly adjacent to the light blocking member; and a second subpixel directly adjacent to the first subpixel, and wherein a length of an upper edge of the first subpixel is longer than a length of an upper edge of the second subpixel, or a length of a lower edge of the first subpixel is longer than a length of a lower edge of the second subpixel. ### Claim 2 (depends on 1) The display device of claim 1, wherein a pixel electrode disposed in the plurality of pixels, respectively, wherein the pixel electrode has a horizontal stem, a vertical stem, and a plurality of fine branches, wherein a size of the first pixel is smaller than a size of the second pixel. ### Claim 3 (depends on 2) The display device of claim 2, wherein a shape of the fine branch disposed in the first pixel is different from a shape of the fine branch disposed in the second pixel. ### Claim 4 (depends on 3) The display device of claim 3, wherein the second pixel is disposed farther from the edge of the substrate than the first pixel. ### Claim 5 (depends on 4) The display device of claim 4, wherein a width of the fine branch disposed in the first pixel is wider than a width of the fine branch disposed in the second pixel. ### Claim 6 (depends on 5) The display device of claim 5, wherein a space between the fine branches disposed in the first pixel is narrower than a space between the fine branches disposed in the second pixel. ### Claim 7 (depends on 4) The display device of claim 4, wherein an angle between the horizontal stem and the fine branch disposed in the first pixel is larger than an angle between the horizontal stem and the fine branch disposed in the second pixel. ### Claim 8 (depends on 4) The display device of claim 4, wherein the plurality of pixels respectively includes: a first subpixel representing a first color; a second subpixel representing a second color; and a third subpixel representing a third color, wherein a size of the first subpixel, a size of the second subpixel, and a size of the third subpixel are substantially the same, and wherein a shape of the first subpixel, a shape of the second pixel, and a shape of the third subpixel are different from each other. ### Claim 9 (depends on 1) The display device of claim 1, wherein the second subpixel is disposed farther from the edge of the substrate than the first subpixel. ### Claim 10 (depends on 9) The display device of claim 9, wherein an area of the second subpixel is substantially the same as an area of the first subpixel. ### Claim 11 (depends on 10) The display device of claim 10, wherein: when the length of the upper edge of the first subpixel is longer than the length of the upper edge of the second subpixel, the length of the lower edge of the first subpixel is shorter than the length of the lower edge of the second subpixel; and when the length of the lower edge of the first subpixel is longer than the length of the lower edge of the second subpixel, the length of the upper edge of the first subpixel is shorter than the length of the upper edge of the second subpixel.
