Description
[technical field]
The utility model is about a kind of display panels.
[background technology]
Display panels generally includes upper and lower two opposing substrates, use sept (Spacer) to separate therebetween, form a space (Cell Gap) and be used for filling liquid crystal, the effect of sept is to keep the constant distance in two substrates gap, thereby the thickness that guarantees display panels is even.
In general, display panels will be realized display characteristics such as high response speed, high-contrast, wide viewing angle, employed display panels must the strict homogeneity that keeps thickness, so the manufacturing process of sept has significant impact to the display performance of display panels.
Usually, the sept of display panels is to spill cloth to substrate with the method for wet type or dry type.Wherein, wet type mainly is to utilize the mode of dispersion spraying to make sept, earlier sept is distributed in the solvent, as freon, alcohol or water-alcohol mixture equal solvent, with spraying plant solvent is sprayed to substrate surface then, sept then is evenly distributed on substrate surface.But the sept wet process has following unfavorable factor: forbidding freon rules, organic solvent cause environmental pollution and fire hazardous, solvent to the damage of alignment film or pollution etc.
Dry type mainly is to utilize gas, as compressed nitrogen etc. sept is directly spilt cloth to substrate surface.Before spilling cloth, utilize electrification by friction usually, make the spacer particles positively charged, spacer particles is spilt cloth and can be spread out because of the repulsive interaction of like electricity nuclear to substrate, so can be uniformly scattered onto substrate surface.On January 16th, 1998, disclosed Japanese patent application JP-A-10-010542 disclosed the method that a kind of dry type is spilt the cloth sept, the sept that this kind method is used comprises spacer particles and the subparticle that sticks to the spacer particles surface, subparticle can improve the flowability of spacer particles, thereby the homogeneity that makes sept be distributed in substrate surface is strengthened.
Dry type and wet type all are to adopt splashing sept processing procedure, and distribution density difficulty is accomplished effective control, cause the sept density unevenness easily and influence the flatness of liquid crystal panel.In addition, sept generally is the pearl material of being made by materials such as silica granule or styrene polymer beads, and the pearl material diminishes evil to the orientation performance of alignment film, thereby and the easy light leak of pearl portion of pearl material influence the contrast of display panels.
When another existing process technique is made display panels, can in the frame glue of bonding upper and lower substrate, add an amount of sept (Rod Spacer), about 0.5～1.5wt%, be used to adjust spacing with the control panel periphery, the material of this kind sept can be glass fibre or silicate, its with need do impregnation after frame glue mixes and handle.If when making by drip (ODF, One DropFill) processing procedure, liquid crystal molecule touches direct and frame splicing, thereby produces the possibility that liquid crystal is subjected to the free micromolecule pollution of frame glue, will directly influence the quality of panel, and occurs the unequal problem of impregnation in the processing procedure easily.
At present, industry has been developed the interval material that can replace the pearl sept, mainly is to utilize photolithographic processes directly to form light spacer on the colored filter surface.
As Fig. 1 and shown in Figure 2, be a kind of liquid crystal panel and the manufacture method thereof that the TaiWan, China patent of on October 21st, 2002 bulletin is disclosed for the 507th, No. 095.This liquid crystal panel comprises upper substrate 171 and the infrabasal plate 179 that is oppositely arranged.Wherein, upper substrate 171 comprises colour element district 174, black matrix" 175 and is arranged on the light spacer 176 on 174 surfaces, colour element district.Infrabasal plate 179 applies the frame glue 177 that is used for bonding two substrates 171,179.In the processing procedure, earlier at infrabasal plate 179 surperficial dispenser methods 178, the bonding upper and lower substrate 171,179 of contraposition forms liquid crystal panel again.
Comprise a step to infrabasal plate 179 dispenser methods 178 in this display panels processing procedure, liquid crystal 178 can directly contact with frame glue 177, frame glue 177 generally is to be made by thermosetting resin, Photosensitive resin or its both potpourri, the liquid crystal 178 that is positioned at the viewing area is polluted by the free micromolecule of frame glue 177 easily, thereby produce the phenomenon of light leak, direct display characteristic to liquid crystal panel is produced harmful effect.In addition, only light spacer 176 is set, is difficult to guarantee that the spacing of liquid crystal panel peripheral clearance equates, thereby influence the display characteristic of liquid crystal panel in 174 peripheries, colour element district of upper substrate 171.
[utility model content]
