Abstract:
1. A display unit, comprising: a plurality of pixels having first to third sub-pixels each of which corresponds to respective colors of red (R), green (G), and blue (B), and a fourth sub-pixel exhibiting higher luminance than the first to third sub-pixels, wherein in each of the plurality of pixels, the first to fourth sub-pixels have light-emitting devices between a pair of substrates that are arranged in opposition to each other, and the first to third sub-pixels are provided with color filters that selectively transmit corresponding color light therethrough on the side of one substrate of a pair of the substrates, and in the fourth sub-pixel, the transmittance of light emitted from the light-emitting device is configured to be reduced at a partial or whole region of the fourth sub-pixel; wherein a pair of the substrates are a driving substrate having a pixel driving circuit and a sealing substrate that is configured of a transparent substrate, and the color filters are provided on the side of the sealing substrate; further comprising a black matrix having apertures in opposition to the first to fourth sub-pixels, wherein the color filter is provided at each of apertures facing the first to third sub-pixels on the black matrix, and a neutral density filter is provided at an aperture facing the fourth sub-pixel on the black matrix: wherein the transmittance of the neutral density filter is configured to be lower at an end region than at a central region.
