Embodiment Construction

[0049] In order to further illustrate the display substrate, the manufacturing method thereof, and the display device provided by the embodiments of the present invention, a detailed description will be given below in conjunction with the accompanying drawings.

[0050] see figure 1 , figure 2 and Figure 7 , the embodiment of the present invention provides a display substrate, including: a display area 30 and a retaining wall structure 20 arranged around the display area 30, the orthographic projection of the retaining wall structure 20 on the base 100 of the display substrate It is grid-like.

[0051] Specifically, the specific structure of the retaining wall structure 20 is various. Exemplarily, the display area 30 of the display substrate is rectangular, and the retaining wall structure is located at the periphery of the display area 30, surrounding the display area At least three sides of 30.

[0052] When encapsulating the display substrate, the encapsulation structur...

Abstract

The invention provides a display substrate, a manufacturing method thereof and a display device, which relate to the technical field of display and aim to solve the problem that cracks generated at the edge of the display substrate are easy to expand into the display substrate to cause packaging failure of the display substrate. The display substrate comprises a display area and a retaining wall structure arranged on the periphery of the display area, and the orthographic projection of the retaining wall structure on the base of the display substrate is in a grid shape. The display substrate provided by the invention is used for displaying a picture.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a display substrate, a manufacturing method thereof, and a display device. Background technique [0002] At present, in order to improve the production efficiency of the display device and reduce the production cost, whether the display device is a thin film transistor liquid crystal display (English: Thin Film Transistor Liquid Crystal Display, TFT-LCD for short), or an organic electroluminescent diode display device (English: : Organic Light Emitting Diode, referred to as: OLED), etc., are all processed on the motherboard and then cut and separated to further complete the back-end module process. [0003] Taking the production of a flexible display substrate including a flexible substrate as an example, a flexible substrate is first formed on a carrier plate, and then multiple display devices are simultaneously fabricated on the flexible substrate in a high-utility arrangement...
