Abstract

Disclosed is a display device wherein: a first substrate 11, a second substrate 12, and a plurality of light emitting elements 10 are provided; light is outputted through the second substrate 12; eachof the light emitting elements 10 is formed by laminating, from the first substrate side, a first electrode 51, an organic layer 70 having a light emitting layer, a second electrode 52, and a sealinglayer 15; a light diffusion layer 80 containing fine particles 81 is formed between the sealing layer 15 and the second substrate 12, and orthographic images of the fine particles 81 in the light diffusion layer 80 do not overlap each other on the second substrate 12; and / or the light diffusion layer is formed between the sealing layer and the second substrate, and the light diffusion layer is configured from a flat section and a plurality of protruding sections that are configured from parts of spherical surfaces protruding from the flat section.

Description

technical field [0001] The present disclosure relates to a display device. Background technique [0002] As a display device for displaying images, an organic electroluminescence display device (hereinafter, also simply abbreviated as "organic EL element") as a light-emitting element (display element) has been developed (hereinafter, Herein, it is also simply abbreviated as "organic EL display device"). In a display device, if reflection of external light is large, display quality deteriorates, and thus reflection of external light must be suppressed. The reflection of external light is roughly divided into two components. One component is a component of Fresnel reflection occurring at the interface between a member constituting the outermost surface of the display device and air, and the other component is emitted to the outside of the display device by light incident on the display device A reflection component is obtained (hereinafter, this reflection component is abbr...
