Description
Technical Field
The utility model relates to a liquid crystal display equipment technical field, in particular to liquid crystal display panel and display device.
Background
LCD (Liquid Crystal Display) includes a color film substrate, a thin film transistor substrate, Liquid Crystal disposed on the thin film transistor substrate, and a support disposed between the color film substrate and the thin film transistor substrate, which is commonly referred to as PS (photo space), where PS generally has two types, i.e., Main PS (Main support) and Sub PS (auxiliary support), and the height of the Main PS is greater than that of the Sub PS. The Main PS is used for maintaining the spacing height between the thin film transistor substrate and the color film substrate in the normal state of the LCD, namely maintaining the stability of the thickness of a liquid crystal box; when the liquid crystal display panel is subjected to external pressure, the Main PS is extruded and shortened, and the Sub PS starts to play a role in buffering and supporting the thin film transistor substrate and the color film substrate, so that the liquid crystal display panel is not easy to damage. After the external pressure disappears, the Main PS elastically restores to the initial state, so that the stability of the thickness of the liquid crystal box is improved.
In the conventional LCD, a step difference is designed for Main PS and Sub PS to realize the function of increasing the thickness of the liquid crystal cell, but actually, the step difference design accuracy of Main PS and Sub PS is difficult to control. If the difference between the Main PS and the Sub PS is too large, the Main PS deforms too much after the lcd panel is subjected to external pressure, and the Main PS cannot elastically return to the initial state, so that the lcd cannot display uniformly. If the difference between the Main PS and the Sub PS is too small, the lower limit of the low temperature of the whole liquid crystal is too narrow under the same liquid crystal quantity, and the display effect is affected.
