Abstract

The invention discloses a display panel and a display device, comprising: a display area and a non-display area arranged around the display area; the display area includes a light-emitting layer arranged on a substrate, and a thin-film encapsulation layer is arranged on the side of the light-emitting layer away from the substrate; The thin film encapsulation layer includes at least one organic layer, and the organic layer extends into the non-display area; in the direction perpendicular to the plane where the substrate is located, the height of the organic layer at the corner of the display area is h1, and the height of the organic layer at the side of the display area The height is h2; wherein, h1>h2. Compared with the prior art, it can effectively prevent subsequent film layers from being broken, disconnected, etc. at the corners of the display area, which is conducive to improving the pass rate of the display device.

Description

technical field [0001] The present invention relates to the field of display technology, and more particularly, to a display panel and a display device. Background technique [0002] With the continuous development of display technology, the manufacturing technology of the display screen is becoming more and more mature. Currently, display screens mainly include liquid crystal display (Liquid Crystal Display, LCD), plasma display (Plasma Display Panel, PDP), organic electroluminescence display (Organic Light Emitting Diode, OLED), etc. Due to the advantages of high brightness, low power consumption, wide viewing angle, and high response speed, light-emitting display screens are increasingly being used in various high-performance display fields. [0003] Existing organic electroluminescent display screens usually use thin-film packaging technology to encapsulate the light-emitting device inside to protect the light-emitting device, but during the packaging process, the packa...
