Liquid crystal molecule is set, there are many tiny electric wires vertically and horizontally for two panels glass substrate centre, control liquid crystal whether by being powered
The light refraction of backlight module is come out and generates picture by molecular changes direction.
Usual liquid crystal display panel is by color film (Color Filter, CF) substrate, thin film transistor (TFT) (Thin Film
Transistor, TFT) substrate, the liquid crystal (Liquid Crystal, LC) that is sandwiched between color membrane substrates and thin film transistor base plate
And frame adhesive (Sealant) composition.Frame adhesive is generally made of acryl, epoxy resin, light initiator etc., passes through heating, purple
The irradiation of (UV) light or two kinds of modes having concurrently realize solidification outside, bond CF substrate and TFT substrate.In order to avoid LCD display
Plate light leakage, it will usually which in panel and the setting of panel surrounding is used for the black matrix" (Black Matrix, BM) of shading, with face
The designs such as the narrow frame of plate occur, and frame adhesive can be coated on black matrix" upper surface by the prior art, to increase display area face
Product.As shown in Figure 1, be a kind of structural schematic diagram of existing liquid crystal display panel, including the TFT substrate 100 that is oppositely arranged with
