状態で全体温度を上げシール接着材3を加熱硬化する。Conventional technology A method for manufacturing a liquid crystal display device in which liquid crystal is sealed between two electrode-attached substrates is to bond two substrates together, such as bonding one substrate with an adhesive applied to the sealing turns and the other substrate. Layer them together via spacers and use weights! A common method is to heat and cure the seal adhesive while applying pressure to 12 substrates. FIG. 6 shows an explanatory diagram of such a conventional bonding method, in which a sealing adhesive 3 containing a spacer material is applied to one of the two electrode-attached substrates 1 and 2. Cells 5 stacked one on top of the other with spacers 4 interposed therebetween are stacked alternately with sheets 6, and a load 8 is applied with a spring or weight via a suppression board. In this state, the entire temperature is raised to heat and harden the seal adhesive 3.

た。Such a method causes variations in the uniformity of the pressure applied to the cell 5, and therefore there is a limit to the thickness accuracy of the cell gap. Particularly for large-area liquid crystal display devices and active materials that undergo a multilayer thin film process and have large substrate warpage)
In the case of J-wax liquid crystal display devices, this is an even bigger drawback. FIG. 7a shows an example of a conventional pressurizing method that improves this point. For example, instead of using a heat-resistant polyimide sheet 6, a pressure plate 7 presses a cell 5 through a silicone rubber block 9 to apply a load of 8. Add. Even in such an example in which the uniformity of the pressure applied to the cell is improved, the pressure distribution becomes 1o as shown in Figure 7, and the load applied to the seal 3 located around the substrate is smaller than that at the center, and the seal When the adhesive is highly adhesive, the cell gap can only be narrowed to a predetermined gap determined by the spacer material mixed in the sealing adhesive, making it difficult to obtain uniformity of the gap.

Therefore, it is an object of the present invention to provide a manufacturing method for realizing a liquid crystal display device having high contrast and high quality image quality performance with little vortex unevenness. Although the drawbacks of conventional bonding methods are as described above, the present invention is particularly effective in manufacturing methods for simple matrix or active matrix liquid crystal display devices for large-area, high-definition image display. In devices, the key to achieving high image quality is the ability to achieve high gap accuracy, and it was not possible to achieve satisfactory viewing and display performance using conventional bonding methods.

完成液晶セルとなる。FIG. 1 shows a state in which a cell 19 according to an embodiment of the present invention is bonded and pressed. FIG. 3 shows a plan view a and a cross-sectional view of the annular elastic body 20 used for this bonding and pressing. As shown in FIG. 1, the annular elastic body 2o located above the seal 17 of the cell 19 placed on the base 21 is fitted into the sealing groove provided in the holding member 22 of this elastic body.
Cell 19 is pressed onto the seal. (Means for pressurization and clamping are not shown.) Gas pressure 26 is applied from the outside through a vent 25 to the space 24 surrounded by the cell, the annular elastic body, and the holding member. In this state, the seal is cured by heating or ultraviolet irradiation, liquid crystal is injected through the injection port in vacuum, the seal is sealed, and polarizing plates are attached to the front and back surfaces to form a completed liquid crystal cell.

減じる方向に働く。Note that the load on the seal is different when the seal is pressed by an annular elastic body without applying gas pressure, and when gas pressure is applied. That is, when gas pressure is applied, the reaction force that the holding member receives due to the gas pressure acts on the seal in a direction that reduces the pressing force.

れた。FIG. 2 shows a thermal expansion type pressurizing jig showing a second embodiment of the present invention, in which an annular elastic body 20 is fitted into a sealing groove 28 provided in a holding member 27 to seal the seal 19. This elastic body 20 presses on 17. The two holding members 27 are held in a clamped state by a support bolt 29 and a nut 3o via a spring 31. Stainless steel is used for the holding member and the support bolt, and silicone rubber is used for the annular elastic body.The seal is thermally hardened by placing the assembly in a heating furnace with the press jig shown in FIG. 2 installed. Due to this heating, the dry N2 filling the space 32 surrounded by the cell 19, the holding member 27, and the annular elastic body 2o thermally expands, and gas pressure is applied to the liquid crystal cell 19. At this time, the 10 vanes made of pressed silicone rubber tend to increase as the temperature rises, but this can be offset by selecting the rigidity of the spring 31. Figure 4 shows experimentally verified data on the internal pressure of the pressurizing jig shown in Figure 2, and shows the internal pressure and jig temperature (
A change in the temperature of the holding plate over time of 0.4 atm was actually measured. A seal bonding experiment was carried out with the initial load applied to the silicone rubber set at 5 KP, and the cell gap accuracy after liquid crystal injection was examined, and gap uniformity within ±0.2 μm was obtained.
