Problems solved by technology

However, even if the concave-convex surface is formed in each layer, since the adjacent layer itself does not change in the laminated film, there is no change in the adhesion between the layer located below and the layer laminated above it, so it may not be possible to suppress the layer. Stripping
[0009] In addition, in the display device using the above-mentioned conventional light-emitting elements, if the uneven surface is to be formed on a plurality of layers arranged on the convex structure, the surface unevenness becomes smaller due to the thickness of the lower layer as the upper layer goes up, and the uneven surface becomes smaller due to the thickness of the lower layer. Planarization of the surface weakens the adhesion between adjacent layers in the stacking direction, which may cause interlayer delamination

Abstract

A display device is provided including a first substrate provided with a pixel, the pixel being provided with a light emitting region of a light emitting device formed by stacking a first electrode, a light emitting layer and second electrode in this order, a first insulating layer having an opening exposing the first electrode at a position corresponding to the light emitting region and provided above the first electrode, a second insulating layer having a certain thickness provided over the first insulating layer and outer region of the opening, and a sealing film provided covering the light emitting device above the second electrode.

Description

technical field [0001] The present invention relates to a display device using a light emitting element. Background technique [0002] An organic electroluminescence element using an organic electroluminescence material (hereinafter also referred to as a "light-emitting element") can emit white light by selecting an organic material or by setting the structure of the light-emitting element to an appropriate structure. The visible light band realizes the emission of each color. Therefore, the development of display devices and lighting fixtures using light-emitting elements has progressed. [0003] A display device using a light-emitting element includes a light-emitting element in each pixel, the light-emitting element of each pixel is connected to a transistor, and light emission is controlled by the transistor. A light emitting element is formed on an element substrate on which transistors are formed. The display device comprises a pixel array in which pixels are arrang...
