An orientation treatment such as oblique vapor deposition is performed, and the upper and lower panel glass plates l are aligned so that the molecular axes of the liquid crystal are twisted, spacers 4 are inserted to maintain uniform spacing, and fixed with adhesive. The liquid crystal 3 is sealed in this liquid crystal cell to form a liquid crystal display panel. [Problems to be Solved by the Invention] However, in the above-mentioned prior art, Vilex, which has strong chemical durability, is generally widely used as the material for the upper and lower panel glass sheets. However, it has the drawback of being expensive and not economical. Therefore, it would be better to use inexpensive soda glass, but the elution of alkali metals and the like contained in soda glass will significantly shorten the life of the display panel. Therefore, it is impossible to use soda glass directly in liquid crystal cells. It is necessary to perform appropriate surface treatment to improve chemical durability. Conventional surface treatment methods for soda glass include:
There is a method of forming a SiO* film on soda glass by sputter deposition. Also silicon hydride (t!
S by CVD treatment using silane)
i Om I! There is a formation method. However, with these methods, it was impossible to form a film on both sides, and the liquid crystal panel warped, making it unapplicable. In particular, concave warping is likely to occur on one side of the panel glass plate on which a protective film such as the above-mentioned 510 m film and transparent electrode are formed, and therefore, the gap between the panel glass plates is were sometimes uneven. Therefore, there has been a problem that the response characteristics and optical characteristics of the liquid crystal display device are affected, and uniform display cannot be obtained. Therefore, the present invention aims to solve these problems.
The purpose is to provide a liquid crystal display device with uniform gaps between panel glasses.

[Example] First, the method is characterized by comprising an electrode made of material, and a silicon oxide film formed on the opposing inner surface of the panel glass plate and on the surface opposite to the surface on which the electrode is formed. , a method of forming a protective film made of a SiOx film or the like will be described. In this example, alkoxysilicate is used as the main ingredient, alcohol (e.g. methyl alcohol, ethyl alcohol, propanol, n-butyl alcohol, isopropyl alcohol) and acid (e.g. acetic acid, hydrochloric acid, nitric acid, sulfuric acid, xylic acid, butyric acid) or water. The treatment agent is dissolved in a mixed solvent. As a treatment method, first, the soda glass is coated with a spinner method, a spraying method, a dipping method, a brush coating method, or the like. Next, alcohol drying is performed at a suitable temperature in the range of 100 to 200°C. This condition allows the final treatment film thickness to be controlled. Furthermore, at 500℃, which is just before the softening point of soda glass,
Firing is performed for 3 hours, and sufficient mechanical film strength can be obtained by this firing. However, with a treatment agent containing only alkoxysilicate, the M film obtained is almost a silica-based coating, and firing at 500° C. does not completely form a continuous layer of silica-based glass, resulting in a lack of chemical durability. Considering the softening point of soda glass, the firing temperature cannot be raised above 500°C, so there is an urgent need to consider a processing solution that can form a film with the same chemical durability as Pyrex when fired at 500°C. It became. Therefore, an organic metal compound such as a bridged boron compound, an aliiso aluminum compound, an organic lead compound, an organic titanium compound, an organic phosphorus compound, an organic lead compound, etc., or a pre-dispersed organic compound is added to the alcohol and acid treatment solvent for the alkoxysilicate described above. Inorganic acid salts such as hydrochlorides, nitrates, and sulfates of metals (aluminum, lead, titanium, zinc), calcium, phosphorus, barium, potassium, sodium, etc., or all-fit salts of the above substances such as phosphoric acid, acetic acid, etc. alone in an appropriate proportion. Alternatively, several substances may be adjusted in a range of 0-1 to 30%. This solvent is applied by a spinner method, a dipping method, a brush coating method, etc., and lθ ~
Dry for an appropriate period of 60 minutes. Further 400℃~50
Bake at 0°C for 2 to 3 hours. 1! ! The resulting coating was able to significantly increase chemical durability. Also. The film thickness can be freely controlled from 500 to 2,000 people, and various types of glass films can be formed by blending various compounds in appropriate proportions, and the chemical durability is equivalent to or better than Pyrex. The above effects were obtained. If the thickness of the thin film is less than 500, the alkali gold V5 elution cannot be prevented, and if it exceeds 2000, cracks are likely to occur. Next, a specific example will be shown. First, tetramethoxysilane: trimethoxyboron: trimethoxyaluminum: sodium acetate: lead acetate = 6
8.4%: 19-5% = 4.5% = 3.8% = 3.8%
This mixed solvent is diluted with methyl alcohol acetic acid to about 10% to obtain a SiO-film forming agent. A panel glass plate made of soda glass is immersed in this SiO□ film forming agent and spun off with a spinner to obtain a uniform coating film. After that, it is dried with alcohol in a constant temperature bath at 150°C. This drying was carried out for about 30 minutes, and further baking was carried out at 500°C for 2 hours. S formed in this way
The surface treatment film 5 made of the iOt film was formed as a uniform coating on both sides of the panel 4N1, as shown in FIG. Transparent electrodes 2 were formed on the opposing inner surfaces of the panel glass plate l on which the surface treatment film was formed on both sides as described above, and then the electrodes were attached to the opposite sides through spacers 4 to complete a liquid crystal cell. A liquid crystal display panel was made by filling a liquid crystal cell with liquid crystal 3. The pair of panel glass plates of the liquid crystal display panel constructed in this way was able to achieve a uniform display without warping as in the conventional case. Effects of the Invention J As described above, according to the present invention, since silicon oxide 19 is formed on both sides of the panel glass plates constituting the liquid crystal cell, warping of the panel glass substrates is prevented and the gap between the panel glass substrates is The gap can be made uniform.Furthermore, the silicon oxide film can also prevent impurity ions from eluting from the panel glass plate.
