Abstract:
1. A mask for forming a black matrix for a display device that includes a data line having a bending structure with respect to a central portion of a pixel region, comprising: an edge frame having a rectangular shape; and a base plate disposed on the edge frame and including a light-transmitting portion and a light-blocking portion, wherein the light-transmitting portion includes first light-transmitting patterns and light-controlling portions between adjacent first light-transmitting patterns, and the light-transmitting portion includes a bending portion corresponding to the central portion of the pixel region, wherein the bending portion is disposed at a same distance from the first light-transmitting patterns adjacent thereto, wherein the first light-transmitting patterns are spaced apart from each other, have their centers defining a centerline, and each of the first light-transmitting patterns is entirely surrounded by the light-controlling portions and the light-blocking portion, wherein a second light-transmitting pattern is disposed in the bending portion and is smaller than the first light-transmitting patterns, wherein the second light-transmitting pattern is about ¼ of a size of the first light-transmitting patterns, and wherein the black matrix includes a second bending structure having a bending width along a gate line direction, the bending width being wider within the central portion of the pixel region, and wherein the bending width is widened by an offset of the second light-transmitting pattern from the centerline of the first light-transmitting patterns along the gate line direction.
