Abstract

The invention provides a manufacturing method of a cholesteric liquid crystal film, a cholesteric liquid crystal film and an optical filter. The manufacturing method comprises the steps as follows: a mixture dispersion layer for manufacturing the cholesteric liquid crystal film is formed in a substrate base plate; the mixture dispersion layer is subjected to regional exposure treatment, so that the cholesteric liquid crystal film is formed; and during the regional exposure treatment, each region of the mixture dispersion layer has specific exposure, and the cholesteric liquid crystal film formed in the corresponding region has a specific screw pitch. With the adoption of the technical scheme, the cholesteric liquid crystal film with various colors can be manufactured and formed simultaneously, so that the manufacturing efficiency is improved.

Description

technical field [0001] The invention relates to a preparation method of a cholesteric liquid crystal film, a cholesteric liquid crystal film and an optical filter. Background technique [0002] With the development of liquid crystal display technology, the technology of flexible display is becoming more and more perfect. The color liquid crystal film in the flexible design display device can be made of cholesteric liquid crystal. The method of manufacturing color liquid crystal film through cholesteric liquid crystal includes the following: [0003] Step S101, controlling the temperature at a first temperature so that the liquid crystal film appears red, and the first temperature is about 25 degrees Celsius; [0004] Step S102, irradiating the area to be made red with ultraviolet light, and fixing the liquid crystal in this area; [0005] Step S103, controlling the temperature at a second temperature, so that the area of ​​the liquid crystal film where the liquid crystal is...
