Description
[technical field]
The invention relates to a kind of liquid crystal panel and manufacture method thereof.
[background technology]
Liquid crystal panel structure generally includes two glass substrates, is coated in the frame glue between this two glass substrate and is poured in this frame glue and two glass substrates are formed liquid crystal molecule in the space.
The method that liquid crystal molecule is fed in the space that this frame glue and two glass substrates form generally comprises two kinds.A kind of is injection method, that is: earlier frame glue is coated on the glass substrate, and one or more liquid crystal injection openings are set on this frame glue; Then another glass substrate is fitted with it, and the frame adhesive curing is made two glass substrate strong bonded; In vacuum environment, make liquid crystal inject opening contact liquid crystal again, cancel vacuum subsequently and make liquid crystal molecule under the atmospheric pressure effect, inject the space of this liquid crystal panel.
Another kind of liquid crystal filling method is liquid crystal drop laxative remedy (One Drop Fill), that is: earlier a complete frame glue is coated on the glass substrate; With liquid crystal drip device liquid crystal is distributed in the space that this frame glue and glass substrate formed; In vacuum environment, another glass substrate is fitted with it, and the frame adhesive curing is made two glass substrate strong bonded.
When two glass substrates are fitted, need the spacing of the two is set according to design, and realize that the accurate spacing of this two glass substrate is comparatively difficult usually.
As shown in Figure 1, be a kind of liquid crystal panel that the United States Patent (USP) of April 24 calendar year 2001 bulletin is disclosed for the 6th, 222, No. 603.This liquid crystal panel comprises first substrate 2, be coated in the first frame glue 6 on this substrate 2, be filled in this frame glue 6 and first substrate 2 forms liquid crystal molecule (figure does not show) in the space, and second substrate (figure does not show) of fitting with first substrate 2.This first substrate 2 and second substrate all have an alignment film 7.
This LCD panel manufacturing method comprises the steps: to apply the first frame glue 6 on first substrate 2; Make it to form the space of accommodating liquid crystal molecule; Apply the second frame glue 8 on this first substrate 2, make it periphery, and the spacing of the first frame glue 6 and the second frame glue 8 is between the 10mm to 15mm around this first frame glue 6; On this first substrate 2, scatter interval dose (Spacer); Aligning, fit first substrate 2 and second substrate in vacuum environment; This first frame glue 6 hardens; Remove the second frame glue 8.
This second frame glue 8 can play the effect that keeps the two spacing uniformity, still in fit first substrate 2 and the second substrate process, behind the sclerosis first frame glue 6, need remove the second frame glue 8, that is to say, the first frame glue, 6 bonding two substrates are only arranged in the finished product of this liquid crystal panel.When this kind liquid crystal panel is applied to large size panel, may there be the problem of two substrates bond strength deficiency; During it is applied to, during the small size panel, then may cause frame glue aging, the product reliability is reduced because of external environment factor or frame glue bad.
[summary of the invention]
Problem for the two substrates bond strength deficiency of the liquid crystal panel that overcomes prior art the invention provides the liquid crystal panel of a kind of tool than high bond strength.
