The embodiments of the present invention provide a rubbing roller and a manufacturing method thereof. The rubbing roller comprises a rubbing cloth and a cylindrical roller body. A surface of the rubbing cloth is provided with a tuft array. The rubbing cloth is obliquely wound around the cylindrical surface of the roller body, thereby increasing the density of rubbing loci generated by the tufts. In the embodiments of the invention, with the rubbing cloth obliquely wound around the surface of the roller body, in the rubbing orientation process, the density of the rubbing loci can be increased without increasing the rubbing tuft density of existing rubbing cloth.

The present application provides a display substrate and a display device. The display substrate includes a display region and a non-display region, a surface layer of the display region being rubbed to form an alignment layer, the non-display region being provided with a test electrode, the test electrode including multiple strip-shaped first sub-electrodes, the extending direction of the first sub-electrodes being the same with the direction of the rubbing for forming the alignment layer. By dividing the test electrode into multiple strip-shaped first sub-electrodes and the extending direction of the first sub-electrodes (i.e., the length direction) being the same as the rubbing direction of the rubbing to form an alignment layer, the display substrate can make the alignment of the alignment layer formed by the rubbing consistent and uniform, thereby avoiding the occurrence of Rubbing Mura when the alignment layer is formed by the rubbing.

The present disclosure provides a method for rubbing an alignment layer on a substrate with a plurality of spacers that are arranged in rows and columns and a liquid crystal display panel. The method includes: determining a first rubbing direction and a second rubbing direction in such a manner that the second rubbing direction is an arrangement direction of liquid crystal molecules when the liquid crystal molecules are arranged correctly on the alignment layer, and an angle between the first rubbing direction and the second rubbing direction is greater than or equal to arctan (b/a), where a represents a row pitch between the spacers and b represents a width of one spacer; performing a first rubbing on the alignment layer in the first rubbing direction; and performing a second rubbing on the alignment layer in the second rubbing direction. The second rubbing direction is different from the first rubbing direction.

The present disclosure discloses a manufacturing method of a display substrate, a manufacturing method of a display panel and a display device. The manufacturing method of a display substrate comprises: performing an pre-irradiation on the display substrate with ultraviolet light after completion of alignment of an alignment layer of the display substrate, such that electrons in a metal layer of the display substrate receive energy under this irradiation of the ultraviolet light and thereby transfer, and are distributed uniformly in the alignment layer of the display area of the display substrate. A uniform distribution of charges in the whole display area would not result in the deficiency of non-uniform brightness at the edge of the display area.

The present disclosure provides a method for rubbing an alignment layer and a liquid crystal display panel. The method includes: performing a first rubbing on the alignment layer of a liquid crystal display panel in a first rubbing direction; and performing a second rubbing on the alignment layer of the liquid crystal display panel in a second rubbing direction. The second rubbing direction is an arrangement direction of liquid crystal molecules when the liquid crystal molecules are arranged correctly on the alignment layer. The second rubbing direction is different from the first rubbing direction.
