The embodiment of the invention discloses a liquid crystal display panel and a liquid crystal display device. A first substrate comprises a main spacer, a second substrate comprises a first limiting ring, the first substrate or the second substrate comprises a black matrix layer, the first limiting ring is correspondingly arranged on the peripheral side of the main spacer, and the orthographic projection of the first limiting ring on the plane where the first substrate is located is located in the orthographic projection of the black matrix layer on the plane where the first substrate is located. And under the action of external force, the main spacer only slides in the inner ring space of the first limiting ring. Therefore, the main spacer only scratches the part, located in the inner ring space of the first limiting ring, of an alignment layer. The area of the inner ring space of the first limiting ring is located in the shielding range of the black matrix layer. Therefore, the phenomenon of lighting light leakage is avoided. Therefore, black-scale color spots are avoided, and the yield of the liquid crystal display panel is improved.
Description
technical field [0001] The present application relates to the display field, in particular to a liquid crystal display panel and a liquid crystal display device. Background technique [0002] The liquid crystal display panel has the characteristics of low cost, high resolution, high contrast and fast response, and is one of the most important display panels on the market at present. During the production process of the liquid crystal display panel, various defects appear, thereby affecting the yield rate of the liquid crystal display panel. [0003] Among them, the black-scale stain is the most common defect, and it also has a great impact on the yield rate of the liquid crystal display panel. The formation of black level spots is because when an external force acts on the liquid crystal display panel, the spacer arranged on the side of the color filter substrate will scratch the alignment layer arranged on the side of the array substrate, thereby affecting the rotation of ...
