Problems solved by technology

However, there are also related problems: due to the protrusions on the side of the color filter, the liquid crystal molecules in a certain range around the protrusions have not achieved a good vertical alignment, so even in the front view, there is still a large light leakage, which affects the multi-domain vertical alignment. Improvement of alignment mode contrast characteristics
However, because the liquid crystal of PSVA directly puts the highly active reactive monomer into the liquid crystal, the concentration of the reactive monomer cannot be well managed after recovery, and some chemical reactions will also occur in the reactive monomer, so it cannot be purified and recycled.

Embodiment 1

[0055] Such as Figure 4 As shown, the PSVA liquid crystal panel manufacturing method of the present embodiment includes steps:

[0056] A. Setting an alignment film on the substrate;

[0057] B. Forming an active reactive monomer layer on the surface of the alignment film;

[0058] C. Coating a liquid crystal layer on the surface of the reactive monomer layer;

[0059] D. After the liquid crystal layer is sealed, photo-alignment is carried out.

[0060] The step B includes: the step B includes: putting the solvent for protecting the active reactive monomer into the spray equipment, spraying it on the surface of the alignment film, and then checking the spray effect, if the uniformity of the spray coating is not When the predetermined threshold is reached, the substrate is cleaned and the solvent of the active reactive monomer is sprayed again; vacuum drying is carried out until the uniformity reaches the predetermined threshold. The first cleaning agent used in basic clea...

Embodiment 2

[0088] Such as Figure 5 As shown, this embodiment is further refined on the basis of Example 1. The substrate of the liquid crystal panel includes an array substrate and a color filter substrate. The step A includes: coating an alignment film on the sides of the two substrates facing each other, and then performing heat curing;

[0089] Described step B comprises:

[0090] B1. Coating frame glue on the edge of the display area on the side of any substrate with an alignment film;

[0091] B2. Spray the solvent of the active reactive monomer on the side of any one or both substrates with the alignment film;

[0092] B3. Check the spray effect. If the uniformity of the spraying does not reach the predetermined threshold, clean the substrate and re-spray the solvent of the active reaction monomer; and then carry out vacuum drying until the uniformity reaches the predetermined threshold.

[0093] The step C includes: using liquid crystal pre-dropping process (ODF) to coat liqui...

Description

technical field [0001] The invention relates to the field of liquid crystal display, and more specifically, relates to a method for manufacturing a PSVA liquid crystal panel and the PSVA liquid crystal panel. Background technique [0002] With the development of the information society, people's demand for display devices has increased. In order to meet this demand, several flat panel display devices, such as liquid crystal display devices (LCD), plasma display devices (PDP), and OLED display devices, have been rapidly developed recently. Among flat panel display devices, liquid crystal display devices are gradually replacing cold cathode display devices due to their advantages of low weight, small size, and low energy consumption. [0003] However, the first twisted nematic (TN) and super twisted nematic (STN) liquid crystal display modes have problems such as low contrast and poor viewing angle. With the improvement of people's living standards, the requirements for disp...
