Abstract

The invention provides an array substrate and a display panel. The array substrate comprises: a substrate; a pixel unit located on one side of the substrate and comprising a pixel electrode; a first pixel limiting layer located on the side, away from the substrate, of the pixel electrode, comprising a light absorption material and provided with a plurality of first openings; and a second pixel limiting layer located on the side, away from the substrate, of the first pixel limiting layer, wherein a plurality of second openings used for limiting pixel units are formed in the second pixel limiting layer, the second openings are overlapped with the side wall, facing the first opening, of the first pixel limiting layer, the side wall, facing the first opening, of the first pixel limiting layer comprises a first curved surface, the first curved surface protrudes in the direction away from the substrate, the side wall, facing the second opening, of the second pixel limiting layer comprises a second curved surface, and the second curved surface protrudes in the direction away from the substrate. According to the array substrate and the display panel, external ambient light cannot penetrate through the first pixel limiting layer to irradiate the pixel electrode, the reflection effect of the pixel electrode on the external ambient light is weakened, and the contrast ratio of the display panel is improved.

Description

technical field [0001] The present invention relates to display technology, in particular to an array substrate and a display panel. Background technique [0002] OLED (Organic Light Emitting Diode, Organic Light Emitting Diode) display is a self-luminous display. Compared with LCD (Liquid Crystal Display, Liquid Crystal Display), OLED display does not require a backlight source, so OLED display is thinner and lighter. In addition, OLED display is also Due to the advantages of high brightness, low power consumption, wide viewing angle, high response speed, and wide operating temperature range, it is increasingly used in various high-performance display fields. [0003] The top-emitting OLED display includes a reflective electrode, which has a high reflectivity. The reflective electrode can reflect ambient light to the human eye, causing the human eye to see the reflected light at the pixel unit, which affects the contrast of the display. Contents of the invention [0004]...
