Display panel and manufacturing method thereof

Abstract

The invention discloses a display panel and a manufacturing method thereof. The display panel comprises a substrate; a driving circuit layer which is arranged on the substrate; a planarization layer arranged on the driving circuit layer; first electrodes, light-emitting function layers and second electrodes which are sequentially arranged on the planarization layer, wherein in a plane parallel tothe substrate, the plurality of first electrodes are arranged in an array, the area covered by the orthographic projection of the first electrodes on the substrate is a first area, and the first electrodes are in one-to-one correspondence with the first areas. The surface, close to the first electrode, of the planarization layer of each first area is parallel to the plane where the substrate is located, or, a first inclination angle is formed between the surface, close to the first electrode, of the planarization layer of each first area and the plane where the substrate is located, and the four-direction inclination directions of the surface, close to the first electrode, of the planarization layer of each first area are the same. The invention provides a display panel and a manufacturingmethod thereof, and aims to solve the problem of inconsistent four-direction color cast of an organic light-emitting display panel.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a display panel and a manufacturing method thereof. Background technique [0002] OLED, Organic Light-Emitting Diode (Organic Light-Emitting Diode), also known as organic electroluminescent device, compared with liquid crystal display (LCD) device, organic light-emitting display device is lighter and thinner, has better viewing angle and contrast ratio, etc., so received widespread attention. [0003] When the viewing angle changes from a direction perpendicular to the screen to a direction parallel to the screen, the brightness of the OLED display screen changes, and the brightness decreases as the viewing angle increases, thereby causing color shift. An OLED display panel generally includes sub-pixels of different colors such as red sub-pixels, blue sub-pixels and green sub-pixels, which are used to display color patterns in combination. However, due to the inconsistent brig...
