Abstract

The embodiment of the invention provides an array substrate, an array substrate manufacturing method and a display panel. The array substrate comprises a pixel definition layer, a light-emitting layerand a transparent light guide layer. The pixel definition layer is provided with a first face and a second face which are oppositely arranged, a plurality of grooves are formed in the first face, andthe angle formed by the extension lines of the side face and the bottom face of the groove ranges from 0 degree to 50 degrees. The light-emitting layer is arranged on the bottom surface of the groove. The transparent light guide layer is filled in the groove and is positioned at the side, far away from the bottom surface of the groove, of the light-emitting layer. The groove is filled with the transparent light guide layer, and after light of the light-emitting layer is refracted by the transparent light guide layer, the emergence angle of the light can be increased. In addition, after the groove is filled with the transparent light guide layer, the problem that the bottom of the groove has an angle and is difficult to package can be solved. After the transparent light guide layer is filled, the leveling performance of material during ink-jet printing can be improved, and a thinning effect is brought to ink-jet printing.

Description

technical field [0001] The present application relates to the field of display technology, in particular to an array substrate, a manufacturing method of the array substrate, and a display panel. Background technique [0002] The current mainstream organic electroluminescent display device (Organic Light-Emitting Diode, OLED) evaporation and packaging process is to evaporate the corresponding organic light-emitting diodes in the pixel area divided by the pixel definition layer (PDL) produced by the array process. Luminescent materials are then packaged and protected by physical vapor deposition (Physical Vapor Deposition, PVD), chemical vapor deposition (Chemical Vapor Deposition, CVD) and ink jet printing (ink jet print, IJP) and other processes. In order to prevent color mixing due to the diffusion of evaporated materials, the pixel area is often designed as a pit structure, and organic light-emitting materials are generally evaporated at the bottom of the corresponding pi...
