Curved display device

A curved display device, comprising:

• first and second substrates facing each other and spaced apart from each other, the first and second substrates having a curved shape, wherein the first and second substrates include a first panel portion at a center thereof, and second and third panel portions at respective sides of the first panel portion;
• gate and data lines on an inner surface of the first substrate, the gate and data lines crossing each other to define a plurality of sub-pixels;
• a black matrix on an inner surface of the second substrate, the black matrix defining a plurality of openings such that each opening of the plurality of openings corresponds to a respective one of the sub-pixels;
• and
• a plurality of color filters between the black matrix and the first substrate,
• wherein the black matrix between respective adjacent openings in the first panel portion has first black matrix widths (BM widths),
• wherein the black matrix between respective adjacent openings in the second panel portion has second BM widths,
• wherein the black matrix between respective adjacent openings in the third panel portion has third BM widths,
• wherein each opening of the plurality of openings in the first panel portion has a first opening width (OP width),
• wherein each opening of the plurality of openings in the second panel portion has a second OP width,
• wherein each opening of the plurality of openings in the third panel portion has a third OP width,
• wherein each of the second and third BM widths is greater than the first BM width,
• wherein the second and third BM widths are equal to each other, and
• wherein, in the second and third panel portions, a central line of the black matrix between horizontally adjacent openings is disposed closer to the first panel portion than a respective border line between adjacent overlapping ones of the plurality of color filters of different colors.
