[0049] In the following description, for convenience, a layer having a plurality of concavo-convex portions formed on the interface is referred to as a “concave-convex portion forming layer”.

[0050] In the display device of the present disclosure, the laminated structure may have a form including a light-transmitting region that passes the light output from each of the light output parts, and a light-transmitting region located between the light-transmitting regions. the outside of the area and blocks the light output from the light output part from passing; (concave-convex portion forming layer) on the interface on the light output side. In addition, in this case, the layer formed with a plurality of concavo-convex portions (concave-convex portion forming layer) may have a form including a material that blocks passage of light. Here, as an example of a material that blocks pa...

Abstract

This display device is obtained by arraying a plurality of light-emitting parts 21 covered by a laminated structure 30. The laminated structure 30 is obtained by laminating a plurality of layers, anda light-emitting surface 30A is flat. A plurality of protrusion-and-recess parts 52 are formed on the boundary surface of at least one layer (protrusion-and-recess part shaping layer 51) located inside the laminated structure 30.

Description

technical field [0001] The present disclosure relates to a display device. Background technique [0002] Light emitting diode display devices each including light emitting elements (specifically, light emitting diodes (LEDs)) arranged in a two-dimensional matrix form have been known. In order to obtain a high contrast ratio, among them, the following structure is generally adopted: having an LED covered with a protective layer, having a layer (black matrix layer) including an opaque material formed on the protective layer, and having an anti-opaque material formed on the black matrix layer. Reflective film. However, the light-emitting diode display device with such a structure still has the following problems: for example, under strong ambient light, reflection of the environment near the surface of the light-emitting diode display device may occur on the surface of the light-emitting diode display device, so that The environment is viewed on the surface of the diode displ...
