Substrate, display panel, display device and manufacturing method of substrate

Abstract

The invention provides a substrate which comprises a first substrate body and a flat layer arranged on the inner side of the first substrate body. Concave holes are formed in the flat layer, or protrusions are arranged on the flat layer. The substrate further comprises supporting columns arranged on the flat layer, the fixed ends of the supporting columns are located in the concave holes, or the fixed ends of the supporting columns surround the protrusions on the flat layer. The invention further provides a display panel, a display device and a manufacturing method of the substrate. By using the substrate, the phenomenon that the supporting columns are stressed to move or incline when friction processing is conducted on an orientation film can be effectively reduced, therefore, the yield is increased, and the display effect is improved.

Description

Technical field [0001] The present invention relates to the field of display, in particular to a substrate, display panel or display device for displaying images or characters, and to a method of preparing the substrate. Background technique [0002] Display devices have developed rapidly in the past ten years and are widely used in modern information equipment such as televisions, computers, mobile phones, and digital cameras. Existing display devices include passive light-emitting display devices, such as liquid crystal display (Liquid Crystal Display, LCD) and active light-emitting display devices, such as organic light-emitting display (Organic Electroluminesence Display, OLED). [0003] Wherein, the liquid crystal display device includes a TFT (Thin Film Transistor, thin film transistor) substrate and a color film substrate arranged oppositely, pixel electrodes and thin film transistors are arranged on the inner side of the TFT substrate, and a black matrix layer is arranged o...

AI Technical Summary

Problems solved by technology

[0006] In addition, the use of support columns will also cause a problem. In display devices, including liquid crystal display devices and organic light-emitting display devices, when the two substrates are subjected to an external force that is not perpendicular to the substrates, the two substrates will be slightly deflected, and the deflection The movement may cause some supporting columns to tilt or displace

[0007] Therefore, how to prevent the movement or inclination of the support column caused by friction during the alignment process of the liquid crystal display device, and the problem of inclination or displacement of the support column caused by the external force of the display device, urgently need to be solved by those skilled in the art.
