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

The invention discloses a display panel and a display device. The display panel comprises a first substrate, a second substrate and a spacer structure; the first substrate and the second substrate are arranged in a box-to-box mode, and the spacer structure is arranged between the first substrate and the second substrate; one end of the spacer structure is fixed to the first substrate, and the other end of the spacer structure abuts against the second substrate; a containing groove structure is arranged on the side, close to the first substrate, of the second substrate, and a part of the orthographic projection of the spacer structure on the second substrate is overlapped with the orthographic projection of the containing groove structure on the second substrate. By means of the mode, the spacer structure is more likely to sink into the containing groove structure to be limited, the spacer structure is prevented from scratching an alignment film, and the display effect is prevented from being affected.
Description
technical field [0001] The present application relates to the field of display technology, 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 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 subjected to a 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. [0004] Therefore, how to more easily...
