Abstract

The present invention provides an organic light-emitting display panel and a manufacturing method thereof, and an organic light-emitting display device. The organic light-emitting display panel comprises a substrate, and at least one light-emitting unit formed on the substrate, wherein each light-emitting unit comprises one anode layer, and an organic layer form on the anode layers; the organic light-emitting display panel also comprises pixel define layers arranged at two sides of the anode layers and the organic layer and being in contact with two ends of the anode layers and the organic layer; materials of inner sides of the pixel define layers being in contact with the anode layers and the organic layer are hydrophilic materials, wherein the anode layers are at least partially recessedto form a first arc-shaped groove, and the organic layer is recessed downwards and is abutted against in the first arc-shaped groove. The organic light-emitting display panel can overcome defects ofnon-uniform thickness of the organic layer in the ink-jet printing process, and therefore, the display effect of the organic light-emitting display device is improved.

Description

technical field [0001] The present invention relates to the field of organic light-emitting display devices, in particular to an organic light-emitting display panel, a manufacturing method thereof, and an organic light-emitting display device. Background technique [0002] Since the birth of organic light-emitting display technology, it has developed rapidly due to its advantages such as wide viewing angle, high contrast ratio, wide color gamut, and fast response speed. Each pixel of such a display device consists of a cathode, an anode and an organic layer located between them. Appropriate voltage is applied to the cathode and anode, the holes are from the anode to the light-emitting layer through the hole injection layer and the hole transport layer, and the electrons are from the cathode to the light-emitting layer through the electron injection layer and the electron transport layer, and the two are recombined in the light-emitting layer. glow. [0003] The organic li...
