Abstract

A display device includes a first substrate, a second substrate, and a plurality of light emitting elements. Light is emitted via the second substrate. Each of the light emitting elementsis formed by laminating, from a side of the first substrate, a first electrode, an organic layerhaving a light emitting layer, a second electrode, and a sealing layer. A light diffusion layercontaining fine particlesis formed between the sealing layerand the second substrate. Orthographic images of the fine particlesin the light diffusion layerdo not overlap each other on the second substrate. Alternatively, the light diffusion layer is formed between the sealing layer and the second substrate, and the light diffusion layer includes a flat portion and a plurality of protruding portions each constituted by a part of a spherical surface protruding from the flat portion.
