Problems solved by technology

First of all, friction-aligned polyimide materials are likely to cause problems such as dust particles, static electricity residues, brush marks, etc., thereby reducing process yield, while photo-aligned polyimide materials can avoid these problems, but due to limited material properties, The heat resistance and aging resistance are not good, and the ability to anchor liquid crystal molecules is also weak, which a

Abstract

The invention provides a self-oriented liquid crystal medium composition, a liquid crystal display panel and its manufacturing method. The self-oriented liquid crystal medium composition comprises a first additive material and a second additive material; the first additive material can be anchored on a base plate through a polar group and generates a polymerization reaction under the ultraviolet irradiation; a first polymer layer is formed on the surface of the base plate, and the second additive material has polymerization reaction subsequently; a second polymer layer is polymerized and formed on the surface of the first polymer layer, and the second polymer layer can make the liquid crystal molecule orient vertically; the first polymer layer can prevent impurities in a CF(carrier free) base plate and a TFT (thin film transistor) base plate from spreading to the liquid crystal. The manufacturing method of the liquid crystal display panel applies the self-oriented liquid crystal medium composition to realize the liquid crystal orientation, thus it omits the process of a traditional polyimide orientation film, saves production cost, improves the orientation effect of liquid crystal and promotes the panel reliability.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a self-aligned liquid crystal medium composition, a liquid crystal display panel and a manufacturing method thereof. Background technique [0002] With the development of display technology, liquid crystal displays (Liquid Crystal Display, LCD) and other flat display devices are widely used in mobile phones, televisions, personal Various consumer electronic products such as digital assistants, digital cameras, notebook computers, and desktop computers have become the mainstream of display devices. [0003] Most of the liquid crystal display devices currently on the market are backlight liquid crystal displays, 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. There are many vertical and horizontal small wires between the two gl...
