A display substrate, a manufacturing method thereof and a display device are provided. The display substrate includes: a base substrate, a display region disposed on the base substrate, and a peripheral region disposed at a periphery of the display region, and the peripheral region is provided with a filling area recessed toward the base substrate; the filling area is provided with an alignment mark and a filling material; and the filling material is configured for filling the filling area. The filling material is provided in filling the filling area of the display substrate, to reduce or eliminate a segment difference at the filling area, and further to avoid the incorrect alignment of liquid crystal molecules caused by the segment difference in the rubbing process, and finally to avoid poor display due to uneven display of a display panel in the working process.

Display substrate, manufacturing method thereof and display device

A display panel and a display device are provided. The display panel comprises a first substrate () and a second substrate () provided opposite to each other, and a spacer () provided between the first substrate () and the second substrate (). The spacer () is covered with an alignment film (), both the first substrate () and the second substrate () includes an active display region () and a non-display region (), the spacer () is provided in the non-display region () of the first substrate () and the non-display region () of the second substrate (). A minimum distance value from an edge of the spacer (), which is an edge closest to the active display region () along a rubbing direction of the alignment film (), to the active display region () along the rubbing direction of the alignment film () is within a preset range for avoiding light leakage caused by the spacer. In the case that an aperture ratio is ensured, light leakage due to insufficient strength of rubbing the alignment film () in a partial region caused by shielding of the spacer () is avoided.

A display panel and a display device are provided in the present disclosure. The display panel includes an array substrate, a color filter substrate and a liquid crystal layer arranged between the array substrate and the color filter substrate. A liquid crystal blocking component is arranged between the array substrate and the color filter substrate, a display region of the display panel is divided into at least two display sub-regions by the liquid crystal blocking component which is configured to block liquid crystals from flowing between the at least two display sub-regions.

Display panel and display device

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.
