Abstract: A motherboard, a motherboard of a display panel, a liquid crystal display panel and a display device are provided. The motherboard includes: a base substrate (101, 201), and a plurality of substrate units (102, 202) arranged in a matrix on the base substrate (101, 201); and a line layer (103, 203) insulated from the substrate units (102, 202) and arranged along a preset extending direction (AA?, BB?), which is disposed within a peripheral region of the substrate units (102, 202). Because the line layer arranged along the preset extending direction is disposed within the peripheral space region of the substrate unit, when the alignment film on the substrate unit is aligned by a rubbing process, it can play a role in carding the rubbing cloth used in the rubbing process, to achieve an even rubbing effect, avoid an uneven rubbing phenomenon, and further facilitate improving a picture quality of the display panel.

Abstract: The present disclosure provides a display substrate, a display panel and a display device. The display substrate includes a base substrate and at least one layer formed on the base substrate, and the layer is formed with an alignment mark, which includes a dot array composed of a plurality of dots. With such dot array composed of the plurality of dots, a step or height difference between the alignment mark and portions of the layer around the alignment mark can be reduced, and adverse influence on the rubbing alignment caused by alignment mark can be reduced or eliminated, thereby reducing or eliminating rubbing Mura in the region where the alignment mark is located.

Abstract: A display substrate, a method for fabricating the same, and a display device are disclosed. The display substrate comprises a plurality of pixels; and a plurality of slit patterns, which are arranged between at least two of the plurality of pixels, and comprise a plurality of slits arranged in a rubbing direction. Slit patterns are provided, and each of slit patterns comprises slits in the rubbing direction. Thus, during a rubbing alignment process, the slit patterns can guide a rubbing cloth to move in the rubbing direction. Accordingly, the alignment of the rubbing cloth is prevented from changing in the rubbing process, a good alignment layer is formed, rubbing Mura is avoided, and the lifetime of the rubbing cloth is extended.

Abstract: The present application discloses a method for manufacturing a display substrate. The method comprises: coating all regions of a base substrate with an alignment film; performing a rubbing process on the base substrate coated with the alignment film; and removing the alignment film outside a display region of the base substrate by a photolithography process so as to retain only the alignment film in the display region. The present application further discloses a display substrate manufactured by such a manufacturing method, as well as a liquid crystal cell and a display comprising such a display substrate.
