Abstract
Light-emitting devices with improved frontal luminance are disclosed. In one example, a light-emitting device includes a plurality of light-emitting elements arranged two-dimensionally, a metamaterial, and an optical control layer provided between the plurality of light-emitting elements and the metamaterial. A ratio (L/D) of a distance L between the light-emitting elements and the metamaterial to a size D of a pixel is greater than or equal to 0.2 and less than or equal to 1.8.
