Color liquid crystal display panel and manufacturing method thereof

Abstract

The invention provides a color liquid crystal display panel and a manufacturing method thereof. According the method, red sub pixels, green sub pixels and blue sub pixels are formed through black matrix baffle walls and a dye liquid crystal layer containing dichroism dye. Through the method, production procedures of the color liquid crystal display panel are reduced, the color liquid crystal display panel is simple in structure and low in cost, a traditional color light filter membrane substrate does not need to be manufactured, a polaroid in the prior art is not needed, the production procedures of the color liquid crystal display panel are simplified, the manufacturing cost of the color liquid crystal display panel is reduced, requirements for the backlight brightness are reduced, and the light penetration rate and the light efficiency are improved.

Description

technical field [0001] The invention relates to the technical field of liquid crystal display, in particular to a color liquid crystal display panel and a manufacturing method thereof. Background technique [0002] A liquid crystal display (LCD, Liquid Crystal Display) has many advantages such as a thin body, power saving, and no radiation, and has been widely used. Most of the liquid crystal display devices currently on the market are backlight liquid crystal display devices, which include a liquid crystal display panel and a backlight module. The working principle of the liquid crystal display panel is to place liquid crystal molecules between two parallel glass substrates, and control the liquid crystal molecules to change direction by applying a driving voltage on the two glass substrates, refracting the light from the backlight module to produce a picture. [0003] Usually, the liquid crystal display panel consists of a color filter film (CF, Color Filter) substrate, a...

Problems solved by technology

[0006] However, the color filter film substrate can only allow part of the band of light to pass through, and the light needs to be polarized by polarizers, so the light intensity after passing through the color filter film substrate will attenuate to about 33% of the original, which is the current LCD One of the reasons for the low light efficiency. At the same time, due to the need to install polarizers and the color filter film substrate needs to be made through processes such as coating, exposure, and development, the manufacturing process is relatively cumbersome and the cost is high, which is not conducive to the control of production costs.
