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.
