Abstract

The invention provides a liquid crystal display panel, a method for producing the same and a display device, wherein the liquid crystal display panel comprises an array baseplate, a color film baseplate and a liquid crystal layer filled between the array baseplate and the color film baseplate, wherein a spacer and an isolation frame are also arranged between the array baseplate and the color film baseplate, and the spacer and / or the isolation frame is made from piezoelectric materials. According to the liquid crystal display panel, the spacer and the isolation frame are made from piezoelectric materials, when the liquid crystal display panel is subjected to the action of the outside pressure, the piezoelectric effect is utilized to apply a certain voltage on the piezoelectric cylindrical spacer and the isolation frame which are deformed, so the piezoelectric cylindrical spacer and the isolation frame can be enabled to return to the original shapes, the functions of controlling and stabilizing the thickness of a liquid crystal box are obtained, and the problem that the thickness of the liquid crystal box is difficult to control and stabilize due to the fact that the traditional organic material cylindrical spacer suffers from permanent deformation under the action of the long-term contact pressure is solved.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a liquid crystal panel, a preparation method thereof, and a display device. Background technique [0002] As an optoelectronic product that integrates large-scale semiconductor integrated circuits and flat-panel light source technology with thin-film transistors as control elements and liquid crystals as the medium, thin-film transistor liquid crystal displays are characterized by low power consumption, portability, wide application range, and high quality. Advantages become a new generation of mainstream monitors. [0003] The display quality and overall performance of thin-film transistor liquid crystal displays are largely affected by materials, device structures, and processes. At present, the thin film transistor liquid crystal display is formed by injecting liquid crystal material between the array substrate and the color filter substrate after the array substrate and the...
