Abstract:
1. A subpixel arrangement structure for a display device, comprising: a plurality of pixel groups each including four unit pixels, each of the unit pixels having a red subpixel, a green subpixel and a blue subpixel which form a delta arrangement structure, wherein major axes of openings of the red subpixels of the pixel groups are substantially aligned along only a direction of a column axis, and major axes of openings of the green subpixels of the pixel groups are substantially aligned along only a direction of a column axis, wherein blue subpixels neighboring each other along a direction of a row axis in the pixel groups are disposed so that major axes of openings of the blue subpixels substantially are aligned along only a direction of the row axis that is perpendicular to the column axis, and other blue subpixels neighboring each other along the direction of the column axis in the pixel groups are disposed so that the openings of the blue subpixels are arranged in zigzags along the direction of the column axis, wherein one of the plurality of pixel groups includes a first unit pixel, a second unit pixel positioned adjacent to the first unit pixel in the direction of the row axis, a third unit pixel positioned adjacent to the first unit pixel in the direction of the column axis, and a fourth unit positioned adjacent to the second unit pixel in the direction of the column axis, wherein a distance between the first and third red subpixels of first and third unit pixels is the shortest among those of the first through fourth unit pixels, wherein a distance between the second and fourth green subpixels of second and fourth unit pixels is the shortest among those of the first through fourth unit pixels, and wherein a distance between the first and second blue subpixels of the first and second unit pixels is the shortest among those of the first through fourth unit pixels.
