摘要： A display device improves brightness while minimizing an increase in the number of source drivers. When a value obtained by dividing the length of a display screen in a row direction by the number of pixels in the row direction is a length corresponding to one pixel in the row direction, one period of color arrangement in the row direction is a length corresponding to two pixels. One such period of color arrangement includes two groups of subpixels that include first subpixels of the light's three primary colors of red (R), green (G) and blue (B), that are arranged in a row and that have the same subpixel configuration; and at least one additional subpixel. Scanning lines extending in the row direction and signal lines extending in the column direction are connected to the first subpixels and the at least one additional subpixel.
