Problems solved by technology

[0003] In order to control the uniformity of the thickness of the liquid crystal cell and to have good pressure resistance when the liquid crystal display panel is stressed, a spacer is usually provided between the two substrates of the liquid crystal display panel. When the panel is under pressure test, the force of the spacer will shift and scratch the alignment film layer in the effective display area, resulting in incorrect alignment of the liquid crystal molecules and affecting the display effect of the display panel

Abstract

The present application discloses a display panel and a display device, the display panel includes a first substrate, a second substrate and a spacer structure, the first substrate and the second substrate are arranged in a cell, and the spacer The structure is arranged between the first substrate and the second substrate, one end of the spacer structure is fixed on the first substrate, and the other end is in contact with the second substrate; on the second substrate A receiving groove structure is provided on a side close to the first substrate, and a part of the orthographic projection of the spacer structure on the second substrate overlaps with the orthographic projection of the receiving groove structure on the second substrate . In the present application, the spacer structure is more likely to sink into the accommodating groove structure to limit the position by the above method, so as to prevent the spacer structure from scratching the alignment film and affecting the display effect.

Description

technical field [0001] The present application relates to the field of display technology, and in particular, to a display panel and a display device. Background technique [0002] With the progress of society and the improvement of people's living standards, high resolution, high transmittance, good picture quality, good pressure resistance and low cost make liquid crystal display panels more and more popular. [0003] In order to control the uniformity of the thickness of the liquid crystal cell and make the liquid crystal display panel have good pressure resistance when it is stressed, a spacer is usually arranged between the two substrates of the liquid crystal display panel. When the panel is subjected to a pressure test, the spacers will be displaced and scratched to the alignment film layer in the effective display area, resulting in incorrect alignment of the liquid crystal molecules, affecting the display effect of the display panel. [0004] Therefore, how to limi...
