Filter, CF) and the liquid crystal layer (Liquid Crystal Layer) that is configured between two substrates constituted, traditional liquid crystal
Display device manufacturing process forms liquid crystal display device by array substrate and color membrane substrates by fitting together to box；Array
Substrate and color membrane substrates stick together by sealant, and need to add photonasty introns (PS, Photo in sealant
Spacer), the box for being used to support liquid crystal display panel is thick, and photoresist barricade (PS is arranged on substrate (array substrate and/or color membrane substrates)
Wall, Photo Spacer Wall) prevent liquid crystal from puncturing to sealant.In addition, further including alignment film, alignment film is logical
It is often made of (PI, Polyimide Film) material, surface is formed with orientation texture, to make the liquid crystal molecule being in contact with it
Orientation needed for occurring.Bubble is discharged for the ease of pixel region, using island exposure mask, while in order to save the use for reducing liquid crystal
Amount, thickness of liquid crystal box and introns height repair, however, this change causes the thickness of liquid crystal box of fringe region higher,
And there are polyimide material accumulation on photoresist barricade, thickness of liquid crystal box is uneven, and there is ear light leakage at edge when lighting.
The present invention is directed to existing liquid crystal display panel, is able to solve non-display area polyimide material heap on barricade
Product forms See-saw effect, and then causes thickness of liquid crystal box uneven, which there is technical issues that ear, this reality
It applies example and is able to solve the defect.
