Abstract

The invention provides an OLED device, a manufacturing method thereof, and a display device. The OLED device comprises a source and drain electrode layer, an insulating layer and an organic layer, and the insulating layer is arranged on the source and drain electrode layer; and the organic layer is arranged on the insulating layer and is electrically connected with the source and drain electrode layer. The organic layer is arranged on the insulating layer, it is guaranteed that the organic layer has the electric conduction function while achieving the planarization function, a planarization layer and an anode layer in the prior art are combined into one, the technological preparation process is reduced, and the preparation technological steps are simplified.

Description

technical field [0001] The present application relates to the field of display technology, in particular to an OLED device, a manufacturing method and a display device. Background technique [0002] In an OLED display, electroluminescence is performed through an organic OLED between the cathode and the anode. In the prior art, OLED luminescent materials, cathodes, anodes and other structures are generally prepared on the back plate, and at the same time, a planarization layer is also prepared to ensure the terrain difference caused by the planarization of the underlying substrate, which is beneficial to the uniformity of its film thickness in the subsequent OLED preparation. , which is of great significance for printing OLED technology. [0003] Therefore, in the prior art, two preparation processes of the anode layer and the planarization layer in the OLED device are indispensable, which leads to a cumbersome manufacturing process of the OLED backplane. Contents of the i...
