Abstract

The invention discloses a preparation method of a display panel. The preparation method of the display panel is used for solving the problem in the prior art that an area where the thickness of film is uneven is wide when an ink jet type printing mode is adopted to manufacture alignment film of the display panel. The preparation method of the display panel comprises manufacturing a color film substrate underlay on one side, facing an array side substrate, of the lower portion of a color film substrate; manufacturing a film even-thickness area and a film uneven-thickness area of first alignment film below the color film substrate underlay by using different temperatures of solidification or alignment liquid with different viscosity; manufacturing a thin film transistor substrate underlay on one side, facing the color film side substrate, on the upper portion of the array side substrate; and manufacturing a film even-thickness area and a film uneven-thickness area of second alignment film on the thin film transistor substrate underlay by using different temperatures of solidification or alignment liquid with different viscosity.

Description

technical field [0001] The invention relates to the technical field of liquid crystal display, in particular to a method for manufacturing a display panel. Background technique [0002] Liquid crystal panel display is currently the mainstream flat panel display, widely used in televisions, notebooks, digital cameras, mobile handheld devices and other fields. [0003] In the liquid crystal display panel, in order to make the liquid crystal molecules form a certain orientation, it is necessary to make an alignment film on both sides of the color filter side substrate and the array side substrate in the liquid crystal panel display, and the material of the alignment film is polyimide film (Polyimide Film) , referred to as PI). [0004] However, if figure 1 It is shown that due to the influence of external factors, it is inevitable to form a region with uneven film thickness in the edge region of the alignment film during the process of making the alignment film. The reasons a...
