Embodiment 1

[0046] The manufacturing method of the display panel of the TFT-LCD of the present embodiment, comprises the following steps:

[0047] Make display motherboard:

[0048] An alignment layer is formed on the array mother substrate formed with a plurality of display areas. In this embodiment, its specific way is: as figure 1 As shown, a plurality of array substrate areas 11 are provided on the array mother substrate 1, and each array substrate area 11 includes a coated area 111 and a non-coated area 112. As shown in the figure, the coated area 111 is located on the upper part, and the non-coated area The area 112 is located at the bottom, and a plurality of display areas 12 are formed on the plurality of coating areas 111 in one-to-one correspondence, that is, one display area 12 is set on each coating area 111, and the orientation of covering the display area 12 is formed in the coating area 111 Layer 13 , specifically, an alignment liquid is coated on the coating area 111 to...

Embodiment 2

[0064] This embodiment is basically the same as Embodiment 1, except that in this embodiment, a frame sealant is provided on the periphery of the display area of ​​the color filter mother substrate, the frame sealant is located at the periphery of the display area, and the frame sealant 4 It straddles between the coated area and the non-coated area, and makes a part of the frame of the sealant on the alignment layer, and another part of the frame of the sealant on the non-coated area. Liquid crystal is dripped into the display area of ​​the array mother substrate. The array mother substrate and the color filter mother substrate are boxed together to form a display mother substrate.

[0065] It should be noted that the manufacturing method of the display motherboard is not limited to the method described in Embodiment 1 and Embodiment 2, and the display motherboard can also be manufactured by using the manufacturing method of the prior art.

[0066] The present invention also ...

Abstract

The invention relates to the field and discloses a display panel manufacturing method of a TFT-LCD (thin film transistor-liquid crystal display), wherein the display panel manufacturing method comprises: forming an orientation layer on an array mother substrate with a plurality of display areas, and forming an orientation layer on a colored film mother substrate with a plurality of display areas; arranging a frame sealing adhesive at the peripheries of the display areas of the array mother substrate respectively, or arranging a frame sealing adhesive at the peripheries of the display areas of the colored film mother substrate respectively; instilling a liquid crystal, and combining the array mother substrate and the colored film mother substrate to form a display mother substrate; and using laser to cut the display mother substrate along a cutting line at the periphery of the frame sealing adhesive to form a plurality of display panels. The laser is used to cut the display mother substrate, the surface of the display mother substrate is prevented from being scratched, the edge of each display panel formed through cutting is level and smooth, is burr-free and has no hard spots, the panel does not need to be grinded, the manufacturing procedure is simplified, and the yield of the panel is improved.

Description

technical field [0001] The invention relates to the technical field of liquid crystal displays, in particular to a method for manufacturing a TFT-LCD display panel, a display panel and a display. Background technique [0002] At present, in the field of TFT-LCD (thin film transistor liquid crystal display) manufacturing, in the manufacturing method of the display panel of the prior art, the display area is produced on the array mother substrate and the color filter mother substrate, and the alignment liquid is coated on the display area to form an alignment. Layer, set a sealant around the display area of ​​the array mother substrate or color filter mother substrate, drip liquid crystal, and press to form a display mother substrate. Use the cutter wheel to cut the display mother substrate along the cutting line on the periphery of the sealant to form pre-cut knife marks, and then obtain the panel by splitting. In this method, the cutter wheel often causes LCD screen damage a...
