    摘要： A light emitting display device includes: a plurality of unit pixels, each including a first light emitting region, a second light emitting region, and a third light emitting region. In a unit pixel from among the plurality of unit pixels: the first light emitting region, the second light emitting region, and the third light emitting region are sequentially located along a first diagonal direction having an angle with respect to first and second directions; the first light emitting region and the second light emitting region overlap with each other in the first direction or the second direction; and the second light emitting region and the third light emitting region overlap with each other in the first direction or the second direction.

    摘要： Alight emitting device (10) including a substrate (8), a lens (17) with a refractive index n arranged on a main surface (34) of the substrate (8), and a light emitting region (32) arranged between the main surface (34) and the lens (17) is provided. A surface of the lens (17) is convex and includes a vertex (41) and an end portion (42). In a case where h represents a height between the vertex (41) and the end portion (42), r represents a distance between the vertex (41) and the end portion (42) in orthogonal projection to the main surface, H represents a height between the end portion (42) and the light emitting region (32), and 2a represents a width of the light emitting region(32), relationships of expressions below are satisfied h r-Htanβ, where 2rh/(r 2 +h 2 )=sinθ, sinθ=nsinα, θ-α=β, and nsinβ=sinγ.
