Abstract

The invention relates to a display screen and a display device. A display screen, comprising: an array layer group, the top layer of the array layer group is an interlayer insulating layer; a planarization layer is located on the interlayer insulating layer, and the planarization layer also has an exposed interlayer insulating layer A hole; a pixel defining layer formed on the planarization layer, comprising a first portion and a second portion; the first portion is located in the hole, and the second portion is located on the planarization layer. In the display screen, when the pixel defining layer is subjected to external force, the first part of the pixel defining layer inserted into the hole can prevent the pixel defining layer from moving, thereby protecting the pixel defining layer.

Description

technical field [0001] The invention relates to display technology, in particular to a display screen and a display device. Background technique [0002] In recent years, OLED (Organic Light-Emitting Diode, Organic Light-Emitting Diode) displays have gradually replaced CRT (Cathode Ray Tube, Cathode Ray Tube) displays and become mainstream products in the display market. [0003] In a traditional OLED display, a planarization layer is usually arranged on the array substrate, a pixel definition layer is arranged on the planarization layer, and a light emitting device is arranged in the pixel definition layer. In this structure, when the display screen is impacted by an external force, it is easy to cause pixel damage and affect the display quality. Contents of the invention [0004] Based on this, it is necessary to provide a display screen and a display device in order to solve the problem in the traditional technology that when the display screen is impacted by an extern...
