Patent ID: 10935214

Abstract:
A light-emitting device includes pixels each including subpixels. Each subpixel includes light-emitting elements that emit respective pieces of light of colors different from each other, and a light-shielding film having openings at respective positions where the openings are opposed to the respective light-emitting elements at predetermined intervals. The openings have respective widths different from each other. The widths of the respective openings in a first direction and a second direction are sized to allow the light-shielding film to block a portion of the pieces of light emitted from the respective light-emitting elements and thereby to cause a 45-degree luminance viewing angle to be different between the first and second directions, and are sized to cause color differences (Δu′v′) at a 45-degree chromaticity viewing angle (u′v′) in the first and second directions to be 0.020 or less. The 45-degree luminance viewing angle is expressed in a unit of cd/m2.
