Example Embodiment

[0030] See Figure 3A to Figure 3D , Which shows the flow chart of the liquid crystal alignment process according to the present invention. Such as Figure 3A As shown, a first substrate 32 and a second substrate 34 parallel to the first substrate 32 are provided. The first substrate 32 may be a TFT array substrate, and the second substrate 34 may be a counter substrate. Or it is a color filter substrate (CF substrate). A first conductive layer 321 and a second conductive layer 341 are respectively provided on the surfaces of the first substrate 22 and the second substrate 24 opposite to each other. The conductive layers 321 and 341 may be transparent indium tin oxide films (ITO films). A liquid crystal accommodating space 35 is formed between the two substrates 32 and 34. More specifically, the center is located between the two conductive layers 321 and 341.

[0031] Such as Figure 3A As shown, a liquid crystal composition 350 is poured into the liquid crystal containing space...

Abstract

The invention discloses a liquid crystal alignment process, which comprises the following steps of: supplying a first substrate and a second substrate and forming a liquid crystal accommodating space between the two substrates; pouring a liquid crystal composite into the liquid crystal accommodating space, wherein the liquid crystal composite comprises liquid crystal molecules, a first monomer material and a second monomer material; and applying a voltage between the two substrates to make the liquid crystal molecules arrayed at a preset inclined angle, and performing aeration processing by using mixed multi-waveband beams to make the first monomer material and the second monomer material undergo a polymerization reaction to form a liquid crystal alignment polymer on the opposite surfacesof the two substrates. The liquid crystal alignment process can improve aeration efficiency, shorten manufacturing time and solve the problems of high cost and waste pollution in the manufacturing ofa liquid crystal alignment layer.

Description

technical field [0001] The invention relates to a liquid crystal panel manufacturing process, in particular to a liquid crystal alignment manufacturing process. Background technique [0002] The alignment control technology of liquid crystal molecules is one of the most important basic technologies for manufacturing liquid crystal displays. The quality of the picture displayed by the liquid crystal display is related to the quality of the liquid crystal alignment. Only when the liquid crystal material in the panel is arranged in a stable and uniform manner can a high-quality picture be presented. Generally, thin layers used to align liquid crystal molecules are called liquid crystal alignment layers. [0003] The liquid crystal alignment technology can be divided into multiple types due to different application principles, for example: multi-domain vertical alignment (MVA) technology and polymer sustained alignment (PSA) technology.
