ABSTRACT:
In a liquid crystal display (10) having a curved display surface, long sides of pixel structures (11) are arranged along the curve direction (Y) of the display surface and on a side of counter substrate provided is a black matrix having a black matrix opening (41a) whose length in the curve direction (Y) is not longer than E−L {(T1/2)+(T2/2)+d}/R, assuming that the length of the display surface in the curve direction (Y) is L, the thickness of an array substrate is T1, the thickness of the counter substrate is T2, the size of the gap between the array substrate and the counter substrate is d, the radius of curvature of the curved display surface is R and the length of a long side of a pixel electrode (29) provided in each of the pixel structures (11) is E. It thereby becomes possible to suppress display unevenness resulting from positional misalignment of the two substrates due to curvature and provide a liquid crystal display achieving a high-quality display image.
