Description

The manufacture method of LCD panel
Technical field
The present invention relates to the manufacture method of LCD panel; In particular to fully suppressing the manufacture method that encapsulant is added to the LCD panel in the liquid crystal.
Background technology
In the manufacturing of LCD panel, need 2 glass substrate, bonding with encapsulant with mutual opposed state of transparency electrode and thin film transistor (TFT) battle array will be set in advance on the surface, make its minimum interval that keeps a few μ m degree, and in this interval, seal behind the filling liquid crystal.Here, in the time of will opening glass substrate (being called " female glass substrate ") as the material of substrate greatly, the liquid crystal method of inclosureing below for example adopting is to fill also encapsulated liquid crystals.
At first, under atmospheric environment, female glass substrate is carried out the encapsulant configuration.The area configurations encapsulant that should form liquid crystal cells along a female glass substrate surface.At this moment, not with the full cut-off ring-type, but by being provided with the pattern that liquid crystal is injected the crack of using in the liquid crystal cells (i.e. " inlet "), the configuration encapsulant.Below, one by one this encapsulant pattern is called " seal pattern ".1 female glass substrate is disposed a plurality of seal patterns.Under this state, make 2 female glass substrate bonding, and push and harden.With mutual so bonding 2 female glass substrate and be added with fixing substrate and be called " at the bottom of the adhesive lining ".Then, size is blocked at the bottom of this adhesive lining in accordance with regulations, makes the inlet of each seal pattern appear at the end, thereby obtains the sky liquid crystal cells.The empty liquid crystal cells of obtaining is like this used existing liquid crystal implantttion technique, from inlet liquid crystal is injected inside after, the sealing inlet.
In above-mentioned liquid crystal inclosure method, need carry out operation that 2 female glass substrate are bonding mutually and the operation of enclosing liquid crystal respectively.
In contrast, as the method that can carry out these 2 operations simultaneously, the technology (being called " liquid crystal drippage mode ") that the clear 63-179323 communique of Japan's patent disclosure (patent documentation 1) discloses is proposed.In liquid crystal drippage mode, liquid crystal drop is fallen the substrate surface that forms loop-like seal pattern, and bonding in a vacuum 2 substrates, thereby carry out the bonding and liquid crystal inclosure of substrate simultaneously.Particularly, printing and sealing material on either party's the substrate in 2 substrates that should be bonding mutually, and after liquid crystal drop being fallen either party's substrate, these 2 substrates are bonding mutually.Then, to sealing material irradiation ultraviolet radiation, thus the ultraviolet hardening resin sclerosis that encapsulant is comprised.Then, bake encapsulant, make the thermosetting resin sclerosis that comprises in the encapsulant by heating.The flat 5-232420 communique of Japan's patent disclosure (patent documentation 2) discloses the method that heating bakes encapsulant.
In this liquid crystal drippage mode, along with the miniaturization of liquid crystal board scale and the slimming of plate, the liquid crystal rate of propagation during dropping liquid crystal on the substrate is accelerated.As a result, liquid crystal contact encapsulant is fast.Therefore, under encapsulant and liquid crystal state of contact, carry out sealing material curing, exist encapsulant to dissolve in problem in the liquid crystal.If encapsulant dissolves in the liquid crystal, then liquid crystal is contaminated, causes the liquid crystal property deterioration.
Dissolve in method in the liquid crystal as suppressing encapsulant to a certain degree, can enumerate the method for using the encapsulant that comprises the UV cured material of radical reaction class.Below, this method is described
As mentioned above, comprise ultraviolet hardening resin and thermosetting resin in the encapsulant.Wherein, ultraviolet hardening resin is made up of acryl resin and UV cured material.And UV cured material is divided into UV cured material of cationoid reaction class and the UV cured material of radical reaction class according to the difference of sclerosis principle.The character that the UV cured material of cationoid reaction class has makes beyond the part of irradiation ultraviolet radiation, also carries out sclerous reaction in linkage, and produces Louis (Le イ ス) acid as reaction residues.Therefore, the lewis acid that produces in the sclerous reaction is added in the liquid crystal easily.On the other hand, the UV cured material of radical reaction class only activates the free radical of the molecule that UV cured material comprises in the part of irradiation ultraviolet radiation, to produce sclerous reaction.The UV cured material of radical reaction class does not produce reaction residues when sclerous reaction.Therefore, if use the UV cured material of radical reaction class, when then utilizing the ultraviolet ray irradiation to make the ultraviolet hardening resin sclerosis, reaction residues is not added in the liquid crystal, thereby can suppress encapsulant to a certain degree and dissolve in the liquid crystal.
Yet, even, can not fully suppress encapsulant and dissolve in the liquid crystal with the UV cured material of the UV cured material of radical reaction class as encapsulant.Below, its reason is described.
The thermosetting resin of encapsulant comprises epoxy resin and UV cured material usually.When utilizing heating to bake to make the thermosetting resin sclerosis, under the temperature that is lower than the thermosetting resin hardening temperature, epoxy resin existing temporarily softening after, work at the time point of thermmohardening material softening, make the thermmohardening material have abundant flowability.As a result, thermmohardening material evenly sclerosis easily.Like this, the epoxy resin that comprises in the encapsulant is softening under the temperature that is lower than the thermosetting resin hardening temperature, is added in the liquid crystal with hardened material.Therefore, can not fully suppress encapsulant dissolves in the liquid crystal.
On the other hand, dissolve in method in the liquid crystal, can consider to shorten the softening time of epoxy resin, epoxy resin is hardened rapidly by accelerating the programming rate of encapsulant as suppressing encapsulant.The method that discloses in the above-mentioned patent documentation 2 is by the 2 female glass substrate and the heating plate of alternately laminated coating encapsulant, and pressurizes after with press fixture it all being sandwiched, directly to the surface heating of female glass substrate, and quickening encapsulant programming rate.
Fig. 4 is the figure that explanation is used based on the heat-transferring method in the heating means of prior art.
With reference to Fig. 4, utilize encapsulant 105 bonding 2 female glass substrate 101 and 102.Liquid crystal 106 is filled in the unit that is formed by 2 female glass substrate 101,102 and encapsulant 105.And, on the surface (top among Fig. 4) of female glass substrate 101 of uncoated encapsulant 105 sides heating plate 103 is set.On the surface (bottom among Fig. 4) of female glass substrate 102 of uncoated encapsulant 105 sides heating plate 104 is set again.Like this, 2 female glass substrate 101,102 of alternately laminated coating encapsulant 105 and heating plate 103,104.
In the method that patent documentation 2 discloses, shown in the No.1 A of arrow, at first utilize each heating plate 103,104 respectively to each female glass substrate 101,102 heating.Then, shown in the No.1 B of arrow,, make encapsulant 105 be warmed up to hardening temperature by conducting heat from 101,102 pairs of encapsulants of female glass substrate 105.That is,, female glass substrate 101,102 need be warmed up to the hardening temperature of encapsulant 105 for encapsulant 105 is warmed up to hardening temperature.Therefore, waste the heat energy of the thermal capacity share of female glass substrate 101,102, and need the time for encapsulant 105 is warmed up to hardening temperature.As indicated above, epoxy resin is being lower than under the hardening temperature of thermosetting resin softeningly, thereby for encapsulant 105 is warmed up to hardening temperature and spended time, then Ruan Hua epoxy resin and thermmohardening material are added in the liquid crystal 106.As a result, the method that discloses of above-mentioned patent documentation 2 can not fully suppress encapsulant 105 and dissolves in the liquid crystal 106.
Therefore, the object of the present invention is to provide and a kind ofly can fully suppress the manufacture method that encapsulant dissolves in the LCD panel in the liquid crystal.
Summary of the invention
In order to solve above-mentioned problem, the manufacture method of LCD panel of the present invention, have in wanting bonding mutually 2 glass substrate either party or both sides glass substrate first type surface configuration encapsulant the encapsulant arrangement step, liquid crystal drop fallen the bonding process of the liquid crystal drippage operation of either party's glass substrate in 2 glass substrate, bonding 2 glass substrate and to liquid crystal (6) irradiation electromagnetic wave and to the heating process of encapsulant heating.By encapsulant irradiation being comprised more than or equal to 3 μ m, carry out heating process to electromagnetic wave smaller or equal to the wavelength of 5 μ m.
According to the manufacture method of LCD panel of the present invention, because an electromagnetic part penetrates glass substrate, do not absorbed by glass substrate, electromagnetic wave shines directly into and is clipped on 2 blocks of encapsulants between the glass substrate, can directly heat encapsulant.Therefore, encapsulant can be warmed up to hardening temperature, and glass substrate is not warmed up to the sealing material curing temperature, so can accelerate the encapsulant programming rate.Thus, shorten the softening time of encapsulant, softening encapsulant is difficult to dissolve in the liquid crystal, can fully suppress encapsulant and dissolve in the liquid crystal.
In the manufacture method of LCD panel of the present invention, preferably, carry out heating process by encapsulant irradiation being comprised more than or equal to 4 μ m to electromagnetic wave smaller or equal to the wavelength of 5 μ m.
Thus, the epoxy resin that comprises in the encapsulant further absorbs electromagnetic wave easily, thereby encapsulant efficient is heated up well.
In the manufacture method of LCD panel of the present invention, preferably respectively do for oneself intermediary ground to encapsulant irradiation electromagnetic wave, carry out heating process by 2 glass substrate.
Thus, shine electromagnetic wave, thereby encapsulant is heated up from the both sides that are added in 2 blocks of encapsulants between the glass substrate.
