Manufacturing method of display panel, display panel and display device

Abstract

The invention provides a manufacturing method of a display panel, the display panel and a display device. The manufacturing method of the display panel includes the steps that an alignment layer is formed on the whole face of a mother array substrate, wherein the mother array substrate comprises at least one array substrate body, and each array substrate body is provided with pressed connection areas; the mother array substrate and a mother color film substrate are combined to form a mother display panel, wherein the mother color film substrate comprises color film substrate bodies corresponding to the array substrate bodies on the mother color film substrate in a one-to-one mode; the mother display panel is cut; the portions, on the pressed connection areas, of the alignment layer are removed. By means of the manufacturing method, the display panel and the display device, the situation that as the thickness of the edge area of the alignment layer is uneven, displaying of the periphery of the panel is poor can be avoided, and the situation that as the pressed connection areas are covered with the alignment layer, the lighting anomaly and the module welding anomaly are caused during combining testing can be further avoided.

Description

technical field [0001] The present invention relates to the display field, in particular to a method for manufacturing a display panel, a display panel and a display device. Background technique [0002] Liquid crystal display panel (TFT-LCD) has the advantages of high display quality, low power consumption, and no radiation. It has developed rapidly in recent years and has been widely used in various fields. Existing liquid crystal display panels mainly include array substrates, Color filter substrate and liquid crystal layer, in the existing liquid crystal display panel manufacturing process, it is necessary to coat a layer of alignment film (PI film) on the color filter substrate and array substrate (TFT substrate), so as to realize the display. [0003] figure 1 It is a schematic diagram of manufacturing an alignment film on an array substrate mother board in the prior art. The array substrate mother board 100' includes a plurality of array substrates 110', and each arr...

[0003] figure 1 It is a schematic diagram of manufacturing an alignment film on an array substrate mother board in the prior art. The array substrate mother board 100' includes a plurality of array substrates 110', and each array substrate 110' includes a crimping area 111' located around the array substrate (that is, the Pad area) and the display area (the area within the dotted line frame 112'), the alignment films 120' on each array substrate are formed separately by coating. With the development of liquid crystal display technology, TFT-LCD narrow frame The demand for products is increasing. However, because the narrow frame process requires a smaller edge margin (EdgeMargin) of the alignment film, the narrower the frame, the easier it is for the alignment film to be coated on the crimping area around the array substrate, resulting in Abnormal lighting and module welding (Bonding) during the cell test (CellTest). At the same time, because the edge of the current alignment film will have a non-uniform thickness (Halo) area, the smaller the edge margin of the alignment film (EdgeMargin), the closer the edge of the alignment film is to the display area, the easier it is to cause defects around the panel
