[manufacture method of display device]
The manufacture method of the display device (duplexer) of present embodiment is as follows：From the present embodiment with protecting film After protecting film is peeled off by the transparent facestock with adhesive linkage, via the decompression degassing process being maintained at adhesive linkage under reduced atmosphere, The overlapping laminating in the way of adhesive linkage is connected with display floater by display floater and the transparent facestock with adhesive linkage.The layer of the present invention The manufacture method of stack does not need protecting film stripping process, using the transparent facestock with adhesive linkage without protecting film Down it is also possible to just manufacture display device without protecting film stripping process.
The flow process of the manufacture method of the display device of present embodiment is illustrated in Fig. 8.
The manufacture method of the display device of present embodiment includes following operation S1～S5.
(operation S1)：The protecting film that protecting film is peeled off by the transparent facestock with adhesive linkage being covered by protecting film from adhesive linkage Stripping process.(operation S2)：The transparent facestock with adhesive linkage after protecting film is peeled off is transferred to the transparent facestock of pressure reduction vessel Transfer operation (1).(operation S3)：Transparent facestock with adhesive linkage is configured in the pressure reduction vessel being under reduced atmosphere Portion, carries out the decompression degassing process of the decompression degassing process of adhesive linkage.(operation S4)：The band implemented after decompression degassing process is glued The transparent facestock connecing layer is transferred to transparent facestock transfer operation (2) of laminating apparatus.(operation S5)：With laminating apparatus by display surface Plate (by laminating thing) and the laminating work of the overlapping laminating in the way of adhesive linkage is connected with display floater of the transparent facestock with adhesive linkage Sequence.
(operation S1：Protecting film stripping process)
In this operation, protecting film is peeled off by the transparent facestock with adhesive linkage being covered by protecting film from adhesive linkage.Protecting film Stripping both can implement in an atmosphere it is also possible under reduced atmosphere implement.After protecting film is peeled off, if bonding will carried The transparent facestock of layer is transferred to during the inside of pressure reduction vessel used in operation S3 can not will be transparent with adhesive linkage Facestock exposes in an atmosphere, and is stored under reduced atmosphere, then implement the stripping of protecting film preferably under reduced atmosphere.But It is that, due to due to production equipment etc., the stripping implementing protecting film under reduced atmosphere is often actually highly difficult.Now, that is, The stripping implementing protecting film in an atmosphere is made also not have special problem.From need not in order to protecting film stripping process prepare pressure reduction vessel From the point of view of, preferably implement the stripping of protecting film in an atmosphere.After protecting film is peeled off, preferably to carry out via operation S2 rapidly The decompression degassing process of operation S3.
In the case that the coefficient of rigidity of the superimposed portions of adhesive linkage is sufficiently small, if when protecting film is peeled off by bonding Protecting film to improve the coefficient of rigidity of adhesive linkage, then can be easily peeled off by layer cooling.Additionally, when protecting film is peeled off The deformation of adhesive linkage is inhibited, and can improve the homogeneity of the thickness of the adhesive linkage after peeling off protecting film.As a result, can press down The generation in space when display floater and adhesive linkage are fitted by system.The temperature of cooling adhesive linkage is according to the resin constituting adhesive linkage Vitrification point and different.Temperature using the maximum as the loss moduluses representing in coefficient of rigidity mensure for the vitrification point When spending, below high 40 DEG C about of the temperature preferably than vitrification point.The temperature of lower limit is not particularly limited, but if being extremely Low temperature, then lead to due to the resin used by protecting film become fragile during low temperature, peel off when film may ftracture.Therefore, bonding Preferably more than -30 DEG C about of the chilling temperature of layer.
(operation S2：Transparent facestock transfer operation (1))
In this operation, after protecting film stripping process terminates, the transparent facestock with adhesive linkage after protecting film is peeled off is moved Deliver to the inside of pressure reduction vessel.In this operation, it is possible to use any carrying of the carrying of the transparent facestock with adhesive linkage can be carried out Device.As Handling device, it both can be the carrying dress of the form of the transparent facestock of carry strap adhesive linkage under atmospheric pressure atmosphere Put or under reduced atmosphere the form of the transparent facestock of carry strap adhesive linkage Handling device.
(operation S3：Decompression degassing process)
In this operation, after transparent facestock transfer operation (1) terminates, the configuration of the transparent facestock with adhesive linkage is being in In the state of the inside of the pressure reduction vessel under reduced atmosphere, carry out the decompression degassing process of adhesive linkage.Because after protecting film is peeled off The state exposed in adhesive linkage of the transparent facestock with adhesive linkage, so the gas such as air is absorbed, is dissolved in adhesive linkage.This Outward, the stage before protecting film stripping, also due to the gas-premeable of protecting film, the gas such as air is slightly through protecting film, quilt Absorb, be dissolved in adhesive linkage.Therefore, in this operation, by carrying out the decompression degassing process of adhesive linkage under reduced atmosphere, from And carry out being dissolved in the degassing of the inside of adhesive linkage, the particularly gas of the inside of superimposed portions.
In decompression degassing process, need suitably to set atmosphere pressures and this two parameters of process time.Atmosphere pressures and The optimum of process time is affected by being dissolved in amount of the gas of the inside of adhesive linkage etc..That is, when atmosphere pressures are with processing Between optimum be for example subject to from elapsed time to this operation for the protecting film stripping process or preserve state and adhesive linkage Thickness (volume) etc. impact.As long as finally can set according to experimental result etc. just to make display floater and adhesive linkage The final atmosphere pressures disappearing in space and process time that interface produces.
In decompression degassing process, preferred more than the 5Pa of atmosphere pressures, more preferably more than 50Pa.Additionally, atmosphere pressures are preferred Below 3kPa, more preferably below 1kPa.Additionally, the degassing time under such atmosphere pressures preferably more than 1 minute, more preferably 5 More than minute.The upper limit of degassing time is not particularly limited, if it is considered that economy etc., then preferably less than 5 hours, more preferably 1 Below hour.If atmosphere pressures and degassing time are within the range, can almost completely remove from adhesive linkage and be absorbed The low boiling impurity such as the gases such as the air to adhesive linkage and water.
As long as in decompression degassing process pressure reduction vessel used can by the transparent facestock with adhesive linkage be accommodated in inside, can be It is de-gassed under desired reduced atmosphere and processes, form does not limit.But, such as it is also contemplated that arriving subsequent handling The pitch time of bonding process and decompression degassing process pitch time the form to optimize pressure reduction vessel for the balance.Concrete and Speech, in the case that the pitch time of decompression degassing process is longer than the pitch time of bonding process, the overall production of manufacturing equipment Property carrys out speed limit by the pitch time of the degassing process that reduces pressure.Now, for example preferably use and can receive multiple transparent areas with adhesive linkage The pressure reduction vessel of material.If using this pressure reduction vessel, the transparent facestock with adhesive linkage after decompression degassing process being terminated Preserve the time of regulation in the inside of pressure reduction vessel.If while pressure reduction vessel is used as saturating with adhesive linkage after degassing process The preservation storehouse of bright facestock, the transparent facestock with adhesive linkage is taken out of and is transferred to laminating apparatus as needed, then manufacture and set Standby overall productivity improves.
In addition it is also possible to the entirely transparent facestock with adhesive linkage is not accommodated in pressure reduction vessel, but by transparent facestock Platform etc. is fixed in the face not forming adhesive linkage, and the face that only can have adhesive linkage to the formation of adhesive linkage and transparent facestock is subtracted The formation that the pressure reduction vessel of pressure-off gas is arranged at transparent facestock has the face of adhesive linkage, carries out the decompression degassing process of adhesive linkage.
(operation S4：Transparent facestock transfer operation (2))
In this operation, the transparent facestock with adhesive linkage after decompression degassing process is terminated is transferred to laminating apparatus.This work In sequence, it is possible to use any Handling device of the carrying of the transparent facestock with adhesive linkage can be carried out.Handling device both can be Under atmospheric pressure atmosphere the Handling device of the form of the transparent facestock of carry strap adhesive linkage or under reduced atmosphere carry strap The Handling device of the form of the transparent facestock of adhesive linkage.But, in this operation, with the transparent facestock carrying out before decompression degassing process Unlike transfer operation (1), because the decompression degassing process of the transparent facestock with adhesive linkage is over, if can Can, then in order to not damage the effect of decompression degassing process, preferably use the Handling device that can be carried under reduced atmosphere.Make In the case of the Handling device carried under atmospheric pressure atmosphere, preferably use transfer time short the removing to laminating apparatus Shipping unit.In the case of being transferred under atmospheric pressure atmosphere, within the preferably 3 minutes transfer time of laminating apparatus, more Within being 1 minute well.If being more than 10 minutes to the transfer time of laminating apparatus, the effect of decompression degassing process may Almost completely lose.
(operation S5：Bonding process)
In this operation, with laminating apparatus by display floater and the transparent facestock with adhesive linkage with adhesive linkage and display floater Fit in the state of the mode overlap connecting.Now, by display floater and band bonding preferably in the pressure reduction vessel of laminating apparatus The transparent facestock of layer is fitted under reduced atmosphere.By being fitted under reduced atmosphere, on the boundary of display floater and adhesive linkage It is not likely to produce space at face.After reduced atmosphere is kept the stipulated time by the inside of pressure reduction vessel, release reduced atmosphere, become big Air pressure.Reduced atmosphere during laminating is below 1kPa.In addition, reduced atmosphere preferably 10～500Pa, more preferably 10～200Pa.
From the point of view of production efficiency, from the beginning of the time point that display floater and the transparent facestock with adhesive linkage are overlapped Time to releasing reduced atmosphere is more short better.For example within preferably 1 minute, within more preferably 30 seconds.
After display floater and the laminating of the transparent facestock with adhesive linkage, can be by not completely crued adhesive linkage again Irradiation light or heating, thus promoting the solidification of adhesive linkage, make the solid state stabilisation of adhesive linkage.
It is also possible to be fitted by the following method in the case that transparent facestock with adhesive linkage has flexibility：Band is made to glue Connect layer transparent facestock be in case of bending so that the formation of the transparent facestock with adhesive linkage has the surface side of adhesive linkage raised, will carry The transparent facestock of adhesive linkage is lentamente overlapped with display floater from the lateral another side in one end.By the method, because will The gas existing in space between transparent facestock with adhesive linkage and display floater is extruded on one side from the lateral another side in one end Fitted, so the interface of display floater and adhesive linkage is not likely to produce space.
In the manufacture method of the display device of present embodiment, by arranging the decompression degassing process of adhesive linkage, display surface The final evanescence in space that the interface of plate and adhesive linkage produces.Accordingly it is also possible to by display floater and saturating with adhesive linkage Bright facestock is fitted under atmospheric pressure atmosphere.Laminating under atmospheric pressure atmosphere compared with the laminating under reduced atmosphere, in display floater It is more prone to space with the interface of adhesive linkage.But, be present embodiment manufacture method in the case of, by being subtracted Pressure-off gas disposal, compared with the situation not carrying out decompression degassing process, space is easier to disappear, even if therefore calming the anger using air Laminating under atmosphere, also can suppress the remaining in space.
(action effect)
In the manufacture method of present embodiment, as shown in figure 9, display floater 50 and the transparent facestock 1 with adhesive linkage are pasted After conjunction, immediately in the interface generation space of display floater 50 and adhesive linkage 14.In multiple spaces, in the central part of adhesive linkage 14 The resin of the glued layer of surrounding 14 of space M1 producing surrounds, and becomes airtight space.On the other hand, with regard in adhesive linkage 14 Circumference produce space M2, the weir shape portion 20 due to the glued layer 14 of this space M2 blocks, thus space M2 is not to outside Open, but also become airtight space.In the case of the manufacture method of present embodiment, produce immediately after laminating this Space M1, M2 disappear in almost all after the stipulated time a bit.
The present inventor speculates, the mechanism that the space producing after laminating disappears immediately is as described below.
Figure 10 is the schematic diagram of the mechanism of the volume-diminished for space is described.
As shown in Figure 10 it is believed that during the volume-diminished in space, having tri- steps (process) of P1, P2, P3.
(step P1:The volume-diminished being led to by laminating differential pressure)
Step P1 is following process：Reply after display floater and the laminating of the transparent facestock with adhesive linkage under reduced atmosphere During to atmospheric pressure atmosphere, produce the pressure that is in the space of decompression state and from outside put on adhesive linkage pressure (big Air pressure) between differential pressure, in the presence of this differential pressure, the volume in space reduces.The time of step P1 is, for example, about the several seconds. That is, light after the several seconds from pressure recovery to the time of atmospheric pressure atmosphere, the volume in space drastically reduces.
(step P2：Because in space, gas is absorbed into the volume-diminished leading in adhesive linkage)
Step P2 is following process：The gas being enclosed in space is absorbed, is dissolved in the adhesive linkage being connected with space, Thus the volume in space reduces.The time of step P2 is, for example, about several minutes～several tens minutes.The body in the space in step P2 The speed of the volume-diminished than the space in step P1 for the long-pending speed reducing is slow.For fully carrying out the bonding of above-mentioned decompression degassing In the case of layer, almost it is wholly absent through the space of step P2.On the other hand, before bonding process decompression degassing insufficient, Or in the case of not carrying out the adhesive linkage that decompression deaerates, fully reduce compared with the space of step P2 is after firm laminating, But sometimes it is not wholly absent.
(step P3：The volume-diminished being led to by the diffusion of bonding in the layer gas)
Step P3 is following process：With the surrounding from space for the gas being dissolved in step P2 in adhesive linkage to outside it Diffusion, the gas in space is gradually resorbed, be re-dissolved in the adhesive linkage that connects with space, thus the volume in space 110 reduces. That is, remain in gas concentration in space after step P2 with the gas concentration being dissolved in the adhesive linkage around space substantially In poised state.But this time, because the gas concentration being dissolved in the adhesive linkage around space and the position away from space Gas concentration in adhesive linkage is in nonequilibrium condition, so the surrounding from space for the gas being dissolved in adhesive linkage is further to it Outside diffusion.Through this process, the gas in space is gradually resorbed, be re-dissolved in the adhesive linkage that connects with space.Step P3 Time be, for example, more than a few hours.The speed of the volume-diminished in the space in step P3 depends on the expansion of bonding in the layer gas Scattered speed, therefore slower than the speed of the volume-diminished in the space in step P2.Through step P3, space is almost wholly absent.
Speculated according to above, inventors believe that the allowance of adhesive linkage energy dissolved gas is more, getting in space can be made Many GAS ABSORPTION, it is dissolved in adhesive linkage, space can be made to disappear within the shorter time.Therefore, if as bonding process Pretreatment in advance adhesive linkage is deaerated, then adhesive linkage can absorb, the allowance of dissolved gas improves, and therefore can make space more It is difficult to remaining.The present inventor passes through the effect that the space of the experimental verification manufacture method of the display device of present embodiment disappears Really.In [embodiment] item below, experimental result is illustrated.
