Description
Technical field
The present invention relates to technical field of liquid crystal display, more particularly to a kind of big plate of liquid crystal to be cut.
Background technique
Liquid crystal display device (LCD, Liquid Crystal Display) has thin fuselage, power saving, radiationless etc. numerous
Advantage is widely used.Liquid crystal display device on existing market is largely backlight liquid crystal display device, packet
Include liquid crystal display panel and backlight module (backlight module).Usual liquid crystal display panel is by color film (Color
Filter, CF) substrate, thin film transistor (TFT) (Thin Film Transistor, TFT) array substrate, be sandwiched in color membrane substrates with it is thin
Liquid crystal and sealing glue frame composition between film transistor array substrate.
In the manufacture of liquid crystal display panel, several tft array substrates are arranged on an entire big plate, equally, with
The corresponding several CF substrates of the several tft array substrates are arranged on another entire big plate, in tft array substrate and CF base
Plate to box to form liquid crystal display panel before, be in several base board units (tft array substrate or the CF on wherein one big plate
Substrate) viewing area (Active Area, AA) periphery setting apply tree lace, successively coated using coating apparatus along the painting tree lace
Sealant, so that tft array substrate forms liquid crystal cell (Cell) together with CF substrate bonding, the then cutting line on big plate
(cut line) is cut into multiple liquid crystal display panels.
With the enlargement of substrate size in liquid crystal display panel, liquid crystal display panel caused by liquid crystal box thickness ununiformity is even is bright
It spends non-uniform problem to highlight, therefore, the prior art proposes a kind of method that liquid crystal box thickness ununiformity can be prevented even, that is, exists
The separation pad (Photo Spacer, abbreviation PS) prepared by photosensitive material is set between CF substrate and tft array substrate.It is color
Black matrix" (BM) and colored color blocking layer are formed in ilm substrate, PS is generally formed on black matrix", for making tft array base
Certain spacing distance is kept between plate and color membrane substrates, the part of sealant inner sealing liquid crystal forms viewing area, shows simultaneously
Show that the region outside region and sealant between area and sealant is all the redundant area (area dummy) that cannot show image, seals
It is thick uniformly that the PS in frame glue built-in redundancy area and the PS of viewing area maintain the box between two substrates when being pressurized for substrate, and seals frame
The PS of Jiao Waiburongyuqu prevents array substrate when cutting position is along cutting wire cutting liquid LCD panel for cutting equipment
Array substrate sinkage caused by excessive deformation.
During above-mentioned cutting liquid crystal display panel, inventor's discovery in the prior art can there are the following problems: such as
Shown in Fig. 1-2, the edge of big plate 100 may be clamped to when transport mechanism transmits big plate 100, outside sealant
The auxiliary PS210 of redundant area is usually arranged as the PS wall (wall) of island or strip, and the design of island PS and PS wall are held
Easily PS is caused to fall off (peeling) when big plate 100 transmits, in addition each 110 sealant external redundant area of liquid crystal panel unit
Auxiliary PS210 be also easy to happen and fall off when cutting big plate 100, that it will cause panel foreign matters is bad by PS peeling, thus
Influence the function and yield of product.In this situation, improvement is designed to existing sealant external redundant area PS, just seems ten
Divide urgent and important.
