Abstract

The application discloses a substrate and a liquid crystal display panel comprising the substrate. The substrate includes a display region and a non-display region surrounding the display region; the substrate includes a lining substrate and a first insulating layer disposed over the lining substrate; the first insulating layer covers the display region and at least part of the non-display region; in the non-display region, the first insulating layer is provided with a first groove; the first groove comprises a first sub-groove and a plurality of second sub-grooves communicated with the first sub-groove; the second sub-grooves are located between the first sub-groove and the display area, and the extending direction of the first sub-groove and the extending direction of the second sub-groove are perpendicular to each other. According to the scheme, the phenomenon of the uneven thickness of an alignment film in the display region due to the accumulation of the alignment liquid in the non-display region is improved, so that the incidence rate of unhealthy phenomenon including the uneven brightness of the liquid crystal display panel of the substrate is reduced.

Description

technical field [0001] The present disclosure generally relates to display technology, in particular to touch display technology, and in particular to a substrate and a liquid crystal display panel comprising the same. Background technique [0002] The liquid crystal display panel includes an array substrate, a color filter substrate, and a liquid crystal layer located between the array substrate and the color filter substrate. The array substrate and the color filter substrate can be simply referred to as the substrate of the liquid crystal display panel. [0003] In order to make the liquid crystal display panel have better response speed and display effect, a certain alignment direction is generally set for the liquid crystal molecules in the liquid crystal layer. [0004] An alignment film (Alignment Layer or Orientation Layer) can be formed on the surface of the above-mentioned substrate respectively, and the liquid crystal molecules have a certain alignment direction ...
