Display device and electronic apparatus

A display device and an electronic apparatus, the display device being provided with: a substrate having a main surface; a plurality of light emitting elements disposed on the main surface; and a plurality of structures disposed on the plurality of light emitting elements, and having a side surface perpendicular or substantially perpendicular to the main surface. A refractive index between the structures is lower than a refractive index of the structures, and a pitch of the light emitting elements is three times or less than a pitch of the structures. 一种显示装置和电子设备，该显示装置设置有：基板，具有主表面；多个发光元件，设置在主表面上；以及多个结构体，设置在多个发光元件上，并且具有垂直于或基本垂直于主表面的侧表面。结构体之间的折射率低于结构体的折射率，并且发光元件的间距是结构体的间距的三倍或更小。
