Description
Technical field
The present invention relates to a kind of panel of LCD that is applicable to, refer to a kind of method for making of display panels especially.
Background technology
The use of LCD is that vertical mode is stood on desktop or the platform mostly at present.Yet the liquid crystal molecule that is filled in the panel is subjected to extraneous thermal source, as: the irradiation of backlight, because of the influence of expanded by heating and action of gravity, easily impel liquid crystal molecule to flow towards panel bottom, cause gap, display panels below to increase and cause the phenomenon of irregular colour.Moreover manufacturing technology now still can't make the height of panel internal clearance thing reach consistance, and the amount of liquid crystal that splashes into is wayward, so the panel bottom is easier to take place the problem of irregular colour.In addition, still towards large-area display development, this type of problem is with even more serious for following display demand.
For aforesaid drawbacks, except the image quality of reduction LCD, when using for a long time, easily cause the distortion of panel Lower Half and shorten its serviceable life.Therefore, known have the Lower Half of display panel is adopted the separation material higher with respect to the first half, promptly the gap of panel Lower Half is slightly larger than the panel first half, can take in liquid crystal because of expanded by heating with the reinforced panel Lower Half.Yet the clearance height inequality in this kind panel, so can influence the image quality that its panel shows.Other has the display panels that uses photosensitive type separation material (photo spacer) and scatter-type separation material (scattered spacer) simultaneously, it is the problem that overcomes irregular colour with the characteristic of scatter-type separation material, but the scatter-type separation material easily causes light leakage phenomena, not only make to contrast to descend, also easily produce the problem of separation material gathering or alignment film scratch.In addition, directly each pixel in the panel is independently cut apart in addition, liquid crystal molecule can't globality be connected,, but cause liquid crystal diffusivity variation and follow-up process issues to reduce the panel pressure reduction at position up and down.
The invention human desires solves the above-mentioned known problem that faces, the display panels of the present invention and preparation method thereof of therefore concentrating on studies out.
