Abstract

An embodiment of the present application provides a rubbed alignment substrate, including at least one array substrate, and the array substrate includes a display area and an uneven step area disposed outside the display area. The uneven step region has multiple via holes, and an alignment film is arranged on the display region. A buffer part is also provided on the uneven level difference area, and the buffer part can be used to eliminate the shape change of the rubbing hair caused by the via holes in the uneven level difference area during the rubbing alignment of the alignment film. By setting the buffer part to avoid the change of the shape of the friction bristles caused by the via holes in the uneven step region, the phenomenon that the liquid crystal display panel may appear streaked Mura after the finished product is improved.

Description

technical field

[0001] The present application relates to the field of display technology, in particular, to a rubbed alignment substrate. Background technique

[0002] With the continuous development of display technology and the continuous improvement of users' quality of life, liquid crystal display devices are more and more used in people's daily life, such as vehicle-mounted display devices in vehicles, display devices in smart homes, and the like. When making a liquid crystal display panel, it is necessary to form an alignment film on the alignment substrate of the liquid crystal display panel, and rub the alignment film to form zigzag grooves on the alignment film, so that the liquid crystal molecules can move along the grooves. The slots are neatly arranged to avoid light leakage caused by light scattering. Some existing liquid crystal display products can be found to have striped mura (uneven display, such as the striped mura is whiter in the black state) in the di...
