及びその製造方法に関するものである。[Detailed description of the invention] The present invention provides a liquid crystal cell in which liquid crystal is injected between glass with electrodes,
In particular, the present invention relates to liquid crystals and cells equipped with an ultraviolet ray blocking layer and an antireflection layer, and a method for manufacturing the same.

を防止すると共に表示の見易い液晶セルを提供しようと
するものである。Generally, liquid crystal cells are formed by injecting liquid crystal between two pieces of glass, but if the dog's display is made only of glass, the liquid crystal itself will deteriorate significantly due to external ultraviolet irradiation, and the service life of the liquid crystal display will be shortened. There is a short drawback. In addition, it has been considered to attach a UV cut filter with adhesive to prevent deterioration due to UV irradiation, but although the filter can cut UV rays and prevent deterioration, there is an adhesive layer between the filter and the glass. Due to the presence of the adhesive, the refractive index changes, the reflection from the surface filter makes it difficult to see the liquid crystal display, and air bubbles may be introduced during the bonding process, causing various problems. The present invention has been made to eliminate these drawbacks, and its purpose is to provide a liquid crystal cell that prevents deterioration of the liquid crystal and provides an easy-to-read display.
本発明のもう一つの目的は、製造工程での加熱温度が比

セルの製造方法を提供しようとするものである。Another object of the present invention is to provide a method for manufacturing a liquid crystal cell in which the heating temperature in the manufacturing process is relatively low and does not cause deformation of the glass substrate.

晶セルが得られるのである。The present invention, which was made to achieve these objects, has an ultraviolet cut layer formed of titanium oxide, cerium oxide, or zinc oxide on the surface of the glass constituting the liquid crystal cell, and a UV cut layer formed of titanium oxide, cerium oxide, or zinc oxide, and magnesium fluoride, silicon dioxide, or A liquid crystal cell characterized by comprising an antireflection layer made of either zirconium oxide, and the formation of both layers cuts harmful ultraviolet rays and eliminates surface reflection on the display surface, so that the display can be improved. This makes it easier to see. In addition, since both the ultraviolet cut layer and the anti-reflection layer are formed by the reactive ion blating method, there is no need for adhesives, which eliminates the various disadvantages caused by the presence of adhesives, and eliminates the need for high temperatures when forming each layer. Since the components of the liquid crystal cell such as the glass plate do not undergo distortion due to heat, an easy-to-read liquid crystal cell can be obtained.

Reference numeral 1 shows the entire liquid crystal cell, and the liquid crystal cell has a liquid crystal 5 between a glass 3 having a transparent electrode 2 and another glass 4. It is injected with UV rays and an anti-reflection layer 7 is further laminated on top glass 4.

ツト層6の膜における屈折率は約2.0であった。In this case, the ultraviolet cut layer 6ri is formed of any one of titanium oxide, cerium oxide, or zinc oxide,
The antireflection layer is formed from one of magnesium fluoride, silicon dioxide, or zirconium oxide, respectively. In forming both of these layers, vacuum evaporation method, suction ring method, etc. can be considered, but reactive ion routing method is most suitable. By this reactive ion blasting method, one of titanium oxide, cerium oxide, or zinc oxide can be integrally formed on the surface of the glass plate with a film thickness of about 100 OA. According to this ion grating method, the film can be formed at a glass plate temperature of 100° C. or less, so that no deformation or distortion of the glass occurs due to the influence of temperature. The refractive index of the ultraviolet cut layer 6 thus formed was about 2.0.

るものである。The antireflection layer 7 is laminated on the ultraviolet cut layer 6, and is theoretically coated with one of magnesium fluoride, silicon dioxide, or zirconium oxide by the same reactive ion blating method. It is formed to have a film thickness of λ/4 (thickness at which no reflection occurs). Furthermore, since the refractive index of a silicon dioxide film is particularly high, a highly reactive film must be used. In any case, the ultraviolet cut layer and the antireflection layer are formed by continuously laminating them by a reactive ion grating method without using an adhesive.

果を奏する。As explained above, in the liquid crystal cell and the manufacturing method thereof according to the present invention, the ultraviolet cut layer and the antireflection layer are laminated on the glass surface constituting the liquid crystal cell using reactive ion grating means, so that the liquid crystal itself is irradiated with ultraviolet rays. It has the excellent effect of protecting it from damage, preventing deterioration, and allowing long-term use.
又、反射防止層が形成されることによって、表面がキラ
キラせず、表示がより一層視認し易くなる効果も有する
。Furthermore, by forming the antireflection layer, the surface does not become glittery, and the display has the effect of making the display easier to see.

じないと云う優れた効果も奏する。Furthermore, since the reactive ion blating method is used, it is possible to continuously laminate both layers, which makes it easy to form both layers, and because these laminates are done at a relatively low temperature, there is no need to apply heat to the glass surface. The lamination work can be carried out before or after forming the liquid crystal cell, and furthermore, the glass surface is deformed by heat without causing any distortion, which is an excellent effect.
