Abstract

Provided is a display apparatus using an organic EL device in which blur in a display image to be a problem for the display apparatus is reduced while propagating light propagating through a high-refractive-index transparent layer is efficiently extracted outside. The display apparatus has a configuration in which a high-refractive-index transparent layer is provided on a light exit side of the organic EL device, a light extraction structure is provided on the high-refractive-index transparent layer so as to surround each of subpixels, a visible light absorbing member is arranged between pixels adjacent to each other, and the visible light absorbing member is not arranged in a region between subpixels adjacent to each other within a pixel.

Dependent claims

A display apparatus, comprising

multiple pixels each comprising multiple subpixels having different emission colors,
each of the multiple subpixels comprising an organic electroluminescence device which comprises:
a first electrode;
a second electrode;
and
an organic compound layer comprising an emission layer disposed between the first electrode and the second electrode,
a transparent layer having a refractive index higher than a refractive index of the organic compound layer, disposed on a light exit side of the organic electroluminescence device,
a light extraction structure provided on the transparent layer and an outer side of each of the multiple subpixels, and
a light absorbing member disposed in a region between pixels adjacent to each other and not disposed in a region between subpixels adjacent to each other within each of the multiple pixels.
