Patent ID: 8110978

Claim:
A display device comprising: a pair of substrates in which a plurality of pixels are disposed in a matrix form as a whole, the pixels being configured with pixels corresponding to R (red), G (green), or B (blue), and the pixels corresponding to the R, G, or B having size different from each other; a self-luminous photo-emission element formed in a region corresponding to each of the pixels, on one of the pair of substrates; and a black matrix layer formed in a region corresponding to between the pixels, on the other of the pair of substrates, wherein formula (1) and formula (2) below are satisfied, or formula (1) and formula (3) below are satisfied: 2√3≦(|W BM −W LD |/D) . . . (1), 0.95≦(relative difference of values (W LD /D) among the pixels corresponding to the R, G, and B)≦1.05 (when W LD <W BM ) . . . (2), and 0.95≦(relative difference of values (W BM /D) among the pixels corresponding to the R, G, and B)≦1.05 (when W LD ≧W BM ) . . . (3), where W BM is an opening dimension in the black matrix layer, W LD is a photo-emission region dimension in the photo-emission element, and D is an air length between the photo-emission element and the black matrix layer.
