[0025] figure 1 It is a schematic flow chart of a manufacturing method of a display panel in the prior art. The main description of the process is as follows:

[0026] Use a resin letterpress to coat the PI liquid on the opposite surfaces of the array substrate and the color filter substrate, and heat-cure the PI liquid for the first time to form a PI film; irradiate the PI film with UV polarized light, and perform a second heat curing on the PI film. Secondary thermal curing to form a PI orientation layer with orientation ability; drop liquid crystal on the array substrate, coat the sealant on the color filter substrate, align and bond the array substrate and the color filter substrate; block the display area, use The UV light pre-cures the frame sealant; the third heat curing is performed to complete the box alignment.

[0027] The research of the inventors found that compared with the rubbing alignment method in the prior art display panel preparation method, the photo-al...

Abstract

The invention discloses a display panel, a preparation method of the display panel, and a display device, and belongs to the technical field of display. The preparation method of the display panel comprises the steps of binding a first substrate and a second substrate in a contraposition manner, arranging liquid crystal comprising a photosensitive curing liquid crystal monomer between the first substrate and the second substrate in a clamping manner, irradiating the whole substrate by UV (ultraviolet) polarized light, and completing liquid crystal orientation and frame seal glue precuring. The method simplifies a preparation technology process of the display panel, lowers the cost, and improves the productive capacity. When the whole substrate is irradiated by the UV polarized light, the photosensitive curing liquid crystal monomer forms a polymer grid on the surface of an orientation layer under irradiation of the UV polarized light, so that a surface anchorage force of the orientation layer is increased, and a residual image and a residual shadow of the display panel are improved. The embodiment of the invention further provides the display panel prepared by the preparation method and the display device comprising the display panel.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a display panel, a manufacturing method thereof, and a display device. Background technique [0002] In the field of display technology, liquid crystal display panels are widely used due to their advantages of small size, no radiation, and high resolution. A liquid crystal display panel usually includes a first substrate and a second substrate that are laminated in position, a liquid crystal layer disposed between the first substrate and the second substrate, and a polarizer disposed outside the substrates. An alignment film layer is arranged on the opposite surface of the first substrate and the second substrate to initially align the liquid crystal layer. When the display panel is working, the voltage applied to the electrodes generates an electric field in the liquid crystal layer, which controls the deflection of liquid crystal molecules in the liquid crystal layer and then...
