Embodiment 1

[0022] As for the liquid crystal display panel, its cell thickness is mainly controlled by spacers arranged between the array substrate and the color filter substrate. In the actual application process, the spacers are divided into main spacers and auxiliary spacers according to the functions played by the spacers. When there is no external pressure, the main spacer has been compressed and supports the thickness of the box, playing a major supporting role. When the liquid crystal display panel is subjected to excessive external force, the auxiliary spacer can only play a supporting role. Since the main spacer has already been compressed when there is no external pressure, when the liquid crystal display panel is subjected to excessive external force, its compression amount will further increase, which will easily cause it to break from the middle and fall off from the substrate, resulting in poor display, which seriously affects LCD quality. By increasing the cross-sectional...

Embodiment 2

[0044] This embodiment provides a display device, which adopts the liquid crystal display panel in the first embodiment. Because the capacity of the liquid crystal display panel to bear external force is improved, and the capacity of the cell thickness condition is guaranteed at the same time, the quality of the display device is improved.

Abstract

The invention relates to the technical field of liquid crystal display and discloses a liquid crystal display panel and a display device. A spacer of the liquid crystal display panel comprises a connection portion and a supporting portion, wherein the connection portion and the supporting portion are of an integrated structure. The size of the cross section of the connection portion is larger than that of the cross section of the supporting portion, the connection portion is connected with a first substrate, and the supporting portion supports a second substrate. Due to the fact that the size of the cross section of the connection portion of the spacer is increased, external force needed in fracturing the spacer from the middle of the spacer can be increased, and the capability of bearing external force of the spacer can be improved. With the supporting portion with a small cross section, the elasticity of the spacer can be kept, and the capability of adjusting the thickness of a box of the supporting portion is ensured. Meanwhile, the contact area between the spacer and the first substrate is increased, and therefore the problem that the spacer will be disengaged when bearing large external force is solved.

Description

technical field [0001] The invention relates to the technical field of liquid crystal display, in particular to a liquid crystal display panel and a display device. Background technique [0002] With the development of display manufacturing technology, liquid crystal display (LCD) technology develops rapidly, and has gradually replaced traditional picture tube displays and become the mainstream of flat panel displays. Liquid crystal displays are widely used in televisions, computers, mobile phones and other fields due to their advantages such as light weight, small size, no radiation, good energy saving effect, and high resolution. In the manufacturing process of the display panel of the liquid crystal display, the design and control of the cell thickness is one of the key technologies of the liquid crystal display, which directly affects the quality of the liquid crystal display. [0003] The liquid crystal display panel of the existing liquid crystal display includes an a...
