Abstract

The invention discloses an organic light-emitting display device, which comprises a lower substrate, a packaging layer, at least one light extraction layer, an electrode layer, a light-emitting layer and a functional layer, wherein the electrode layer, the light-emitting layer and the functional layer are arranged between the lower substrate and the packaging layer, and a micropore structure is formed in the light extraction layer. The invention further discloses a manufacturing method of the organic light-emitting display device. The organic light-emitting display device is provided with the light extraction layer with the micropore structure, and enables light to be scattered repeatedly by micropores when getting into the light extraction layer through reasonably setting the position of the light extraction layer, thereby reducing internal reflection at the light extraction layer on the whole, and enabling more light to be extracted and emitted from the light-emitting device. Therefore, the light-emitting efficiency of the device can be substantially improved. In addition, the organic light-emitting display device can be manufactured in a large scale, is low in cost and has important practical application values.

Description

technical field [0001] The present invention relates to the technical field of organic light-emitting semiconductor applications, in particular to an organic light-emitting display device and a manufacturing method thereof. Background technique [0002] OLED (Organic Light Emitting Display) and other self-luminous devices have the characteristics of self-illumination, wide viewing angle, long life, energy saving and environmental protection. With the rapid development of display and lighting industries, OLED has become an important hot spot in display design. [0003] Due to the influence of factors such as indium tin oxide (ITO) and glass substrate, various functional layers inside the organic light-emitting structure, glass substrate and air surface layer, reflection and refraction, about 80% of photons cannot escape into the air. , resulting in low photon utilization. In order to improve the light extraction efficiency of the device, researchers have proposed many method...
