Abstract

The invention discloses an organic light-emitting device. The organic light-emitting device comprises a glass cover plate, a cathode layer and a liquid-state light-emitting layer which are sequentially stacked, wherein one side, facing the liquid-state light-emitting layer, of the glass cover plate is coated with the cathode layer to form a first module, the first module comprises a first surface facing the liquid-state light-emitting layer and a second surface away from the liquid-state light-emitting layer, each of the first surface and the second surface is provided with a scattering layer, and each scattering layer is used for changing the transmission directions of light rays emitted by the liquid-state light-emitting layer so as to increase the efficiency of the light rays entering the first surface and going out of the second surface. The invention further discloses a manufacturing method organic light-emitting device. The organic light-emitting device has the advantages that each scattering layer is annealed after being formed, the visible light transmittance of each scattering layer after crystallization is increased, and the light-coupling efficiency of the organic light-emitting device is increased evidently.

Description

technical field [0001] The invention relates to the field of display technology, in particular to an organic light-emitting device and a method for manufacturing the organic light-emitting device. Background technique [0002] With continuous advancement of display technology, organic light-emitting diode (Organic Light-Emitting Diode, OLED) display panels are more and more widely used in display devices. As an organic light-emitting device, OLED has the characteristics of good elasticity, bendability, unbreakability, and novel appearance. It is the development direction of future display technology and lighting technology. In the OLED device structure, due to the inconsistency of the materials of each film layer, most of the light emitted through the organic light-emitting layer of the device is limited in the device and cannot be effectively output to the outside of the device, that is, the light coupling efficiency is low. How to design OLED The internal structure and ma...
