Liquid crystal display panel manufacturing method and liquid crystal display panel

Abstract

The invention provides a liquid crystal display panel manufacturing method and a liquid crystal display panel. The manufacturing method includes first providing a first substrate and a second substrate, wherein the first substrate is provided with a TFT layer, a color resistance layer, a pixel electrode layer and a light shielding layer, and only a common electrode is disposed on the second substrate; then forming an alignment film on the first substrate, coating a self-aligned liquid crystal material on the first substrate or the second substrate and pairing the first substrate and the secondsubstrate to form a liquid crystal box; then applying a voltage to the liquid crystal box while performing UV illuminating to enable the self-aligned liquid crystal material to undergo reverse polymerization to form a first polymer layer and a second polymer layer on the alignment film and the common electrode respectively. By means of the method, the self-aligned liquid crystal material can be diffused uniformly by improving the flatness of the substrates to avoid poor display.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a method for manufacturing a liquid crystal display panel and the liquid crystal display panel. 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] Generally, a liquid crystal display panel includes a color filter (Color Filter, CF) substrate, a thin film transistor (Thin Film Transistor, TFT) substrate, and a liquid crystal (LC, Liquid Crystal) sandwiched between the color filter substrate and the thin film transistor substrate. On the CF substrate and the TFT substrate in the liquid crystal display panel, there is a layer of thin film mate...

Problems solved by technology

However, there are still some defects when the vertical alignment agent is used for alignment. First, in order to expand the viewing angle, the existing liquid crystal display panels widely use pixel electrodes with a "rice" pattern, and slits are formed in the pixel electrodes. The position is not covered by the electrode material, and the passivation layer formed by silicon nitride or organic insulating material under the electrode layer is directly exposed. When the vertical alignment agent is used for alignment, the effect between the vertical alignment agent and the passivation layer The force is weaker than the force between the vertical alignment agent and the electrode, and it is easy to cause poor alignment, resulting in dark or bright line defects. Secondly, the color filter substrate of the existing liquid crystal display panel is generally formed with a color resist layer, a black matrix, and a common electrode. And spacers, after multiple film layers are stacked, a segment difference will be formed on the color filter substrate, resulting in uneven surface of the color filter substrate, with different terrains, and the vertical alignment agent cannot be uniformly diffused on the color filter substrate, which is prone to occurrence bright spot defect
