Description
Technical field
The present invention is about a kind of display panels (Liquid Crystal Display Panel), the high dielectric anisotropy of particularly a kind of employing (dielectric anisotropy) liquid crystal molecule, and can reduce the display panels that broken bright spot produces probability.
Background technology
Display panels (liquid crystal display panel, LCD panel) compared to existing cathode-ray tube (CRT) (cathode ray tube, CRT), external form is frivolous, power consumption is few and low radiation pollution owing to have, and has risen to the display device that becomes main flow at present.The mode between the substrate in the prior art liquid crystal molecule inserted include vacuum impregnation and liquid crystal drop-method (one drop fill, ODF) etc.Vacuum impregnation is after two substrates is oppositely arranged, to seal around the two substrates with frame glue (comprising the thermmohardening material usually), then with after the sclerosis of frame glue, via an opening of reserving liquid crystal molecule is injected by formed chamber between frame glue and the two substrates, at last again with the sealing compound closure of openings with capillary theory again.But form the mode of display panels with the vacuum inhalation, the thermmohardening material in the frame glue is easy to generate the problem of offset in heating process, and the method is very consuming time, applies on the undersized panel at present more.
Development in recent years goes out a kind of liquid crystal drop-method, adopts the material with photo-hardening characteristic to be used as frame glue.Form the frame glue of a rectangle seal pattern on the first substrate therein of the method, then before frame glue is still unhardened, liquid crystal molecule is splashed in the rectangular seal pattern equably, and at once with another superimposed substrate, make its sclerosis with the UV-irradiation seal pattern then, frame glue can bind two substrates smoothly and can not produce offset.Owing to the time that the liquid crystal drop-method is required is shorter, and the better quality of frame glue sclerosis, therefore manufacturer adopts the liquid crystal drop-method to make display panels more now.
Yet, compared to vacuum impregnation, though above-mentioned liquid crystal drop-method can significantly shorten the time that liquid crystal injects, but the method can make the still unhardened glue of frame completely directly contact with liquid crystal molecule, this can make in the frame glue material because of the close stripping of polarity to liquid crystal layer, and produce the problem of the broken bright spot (around mura) of panel periphery color distribution inequality.Please also refer to Fig. 1 and Fig. 2, Fig. 1 and Fig. 2 form the synoptic diagram of broken bright spot to the liquid crystal layer for display panels center xanthan molecule stripping in the prior art, and wherein Fig. 2 is along the sectional view of AA ' tangent line among Fig. 1.As Fig. 1 and shown in Figure 2, display panels 100 comprises two substrates 102,104 in the prior art; Two alignment films 106,108 are arranged at two inboards of two substrates 102,104; One liquid crystal layer 112 is set in place between two alignment films 106,108; And one frame glue 110 be arranged on two substrates 102,104 around, wherein the liquid crystal molecules in the liquid crystal layer 112 can be positioned in two substrates 102,104 and the frame glue 110 formed cavitys.
Generally speaking, the liquid crystal molecule in the liquid crystal layer 112 can present regular arrangement owing to the orientation function of alignment film 106,108.But as indicated above, when forming frame glue 110, the material close with liquid crystal molecule polarity in the frame glue 110 can dissolve in the liquid crystal layer 112 because of the principle of " similar mixing (like dissolves like) ", and the impurity 114 in the formation liquid crystal layer 112.Impurity 114 partly can be upset the arrangement of original liquid crystal molecule, making liquid crystal molecule have no idea to be produced by the electric field driven reverses, therefore produce permanent bright or permanent dark broken bright spot 116, be dispersed in the intersection (please refer to Fig. 1) of frame glue 110 and liquid crystal layer 112.Naked eyes were discernable when this broken bright spot was serious, can reduce the display quality of display panels 100, also become present display panels to desire most ardently the problem of improvement.
