Abstract

The present invention provides a display panel and a preparation method thereof. The display panel preparation method comprises the following steps: a first substrate preparation step, a second substrate preparation step, a pairing step, and a first alignment film preparation step; and the display panel comprises a first substrate, a second substrate, a liquid crystal layer and a frame adhesive floor. The display panel and the preparation method thereof have the beneficial effects that a first liquid crystal alignment monomer layer is disposed on the surface of a common electrode layer, and acolor film substrate is heated and irradiated by a heat gun, so that the first liquid crystal alignment monomer layer and the common electrode layer are subjected to a link reaction to form a first alignment film layer, to improve the phenomenon of poor alignment, and to avoid gray scale difference of the display panel due to poor alignment, thereby ensuring the yield and quality of products. In addition, the method omits a coating process of polyimide materials during preparation of the color film substrate, removes a friction process, avoids defects caused by the friction process, further improves the yield of the products, and enhances competitiveness of the products.

Description

technical field [0001] The invention relates to the display field, in particular to a display panel and a preparation method thereof. Background technique [0002] A liquid crystal display device (LCD, Liquid Crystal Display) has many advantages such as a thin body and power saving, and has been widely used. Most of the liquid crystal display devices currently on the market are backlight liquid crystal display panels, which include a liquid crystal display panel and a backlight module. [0003] A liquid crystal panel usually includes a thin film transistor array substrate (Thin Film Transistor Array Substrate, TFT Array Substrate), a pixel electrode, a first PI alignment film (polyimide, PI), a liquid crystal layer (LiquidCrystal Layer), a second PI alignment film, a common electrode and a color filter Substrate (ColorFilter Substrate, CF Substrate). When a voltage is applied to the pixel electrode and the common electrode, an electric field will be generated in the liquid...
