To provide a light-emitting device and an electronic apparatus capable of suppressing degradation in image quality under a high-resolution condition.SOLUTION: The light-emitting device in accordance with an embodiment of the present disclosure includes: a plurality of pixels each composed of a plurality of sub-pixels having different emission colors from one another; and a light-shielding film having a plurality of openings having different opening widths from one another provided at positions respectively facing the sub-pixels via a predetermined gap. The opening widths in a first direction and a second direction of each opening are controlled to such sizes that 45° luminance viewing angles (cd/m) in the first direction and the second direction are different from each other because the light emitted from each sub-pixel is partially blocked by the light-shielding film. The opening widths in the first direction and the second direction, of each opening are further controlled to such sizes that a color difference (Δu', v') between the first direction and the second direction of the 45° chromaticity viewing angles (u', v') is 0.020 or less.SELECTED DRAWING: Figure 6 【課題】高解像度において画品位の低下を抑制することの可能な発光装置および電子機器を提供する。【解決手段】本開示の一実施の形態に係る発光装置は、発光色の互いに異なる複数の副画素からなる複数の画素と、所定の間隙を介して各副画素と対向する位置に開口幅の互いに異なる複数の開口部が設けられた遮光膜とを備えている。各開口部の、第１方向および第２方向における開口幅は、各副画素から発せられた光の一部が遮光膜によって遮られることに起因して４５°輝度視野角（ｃｄ／ｍ2）が第１方向および第２方向において互いに異なる大きさとなるような大きさとなっている。各開口部の、第１方向および第２方向における開口幅は、さらに、４５°色度視野角（ｕ'ｖ'）の、第１方向および第２方向における色差（Δｕ'ｖ'）が０．０２０以下となるような大きさとなっている。【選択図】図６
