Abstract
According to an aspect, an image display device includes: first pixels each including sub-pixels of three or more colors included in a first color gamut; second pixels each including sub-pixels of three or more colors, the sub-pixels in the second pixels having luminance higher than the luminance of the sub-pixels in the first pixels, the three or more colors belonging to a second color gamut within the first color gamut; and an image display unit in which the first pixels and the second pixels are arranged in a matrix in a display area, the first pixels and the second pixels being adjacent to each other.
