Abstract

The invention relates to a display panel and a manufacture method thereof. The manufacture method of the display panel includes the following steps: providing a pixel array substrate and an opposite substrate; and forming a boundary layer on the pixel array substrate or the opposite substrate, the boundary layer including a polyimide precursor formed by reacting at least a dianhydride compound and at least a diamine compound and a polyimide obtained through amidation of the polyimide precursor, wherein the polyimide contains at least one diamine compound containing at least a light photoreaction group side chain. The display panel and the manufacture method thereof can reduce a driving voltage when the liquid crystal display panel is driven.

Description

technical field [0001] The present invention relates to a display panel and its manufacturing method, and in particular to a liquid crystal display panel and its manufacturing method. Background technique [0002] In 1888, Friedrich Reinitzer placed cholesteric benzoate in a polarizing microscope and observed that cholesteric benzoate would show different colors (blue Purple and blue), the color change phenomenon between the homogeneous phase and the cholesteric phase only exists in a small temperature range (only about 1 ° C temperature range). In 1970, many scientists used methods such as volumetric analysis and high-resolution differential scanning calorimeter to confirm that the aforementioned phenomenon was a new thermodynamically stable phase, and called it the blue phase (bluephase, BP). [0003] Ordinary liquid crystals are optically anisotropic, but the blue phase is optically isotropic. In other words, the blue phase has very low or even no birefringence. Since ...
