Abstract
An image display device displays an image by using a plurality of display pixels, each display pixel including four sub-pixels corresponding to different colors. The four sub-pixels forming each of the display pixels are located such that two sub-pixels having a smaller level of luminance are located at edges of the display pixel, each of the two sub-pixels being located at either edge of the display pixel, and such that two other sub-pixels are located at a central portion of the display pixel so that an absolute value of a difference between a luminance added value, which is a value obtained by adding luminance levels of one of the sub-pixels located at the edges of the display pixel and an adjacent pixel, and a luminance added value, which is a value obtained by adding luminance levels of the other sub-pixel located at the edge of the display pixel and an adjacent pixel, is reduced.
