間に液晶３３を充填して成るのが通例であった。Conventionally, liquid crystal displays have had a structure as shown in FIG. That is, a transparent plate 31.35 made of glass, on the surface of which a tin oxide substrate 1ids2.34 as a transparent electrode is formed, and two substrates on which an insulating film 36.38 formed by coating liquid glass is formed. It was customary to bond the two plates together with a gap material 37 made of glass bulbs of about 10 microns in between, and to fill the space between the two plates with liquid crystal 33.

が発生し、画像ムラが発生するという問題があった。However, according to the above-mentioned conventional technology, image unevenness does not occur with a small-area liquid crystal display, but with a large-area (4-inch)
In liquid crystal displays of sizes larger than 100 mm), there is a problem in that gap spacing varies, resulting in image unevenness.

基本とする。The present invention aims to eliminate the problems of the prior art and provide a structure and configuration of a liquid crystal display that does not cause image unevenness even in a large-area liquid crystal display. ] In order to solve the above problems, the present invention is based on a method of fusion welding a transparent substrate and a gap material in a liquid crystal display.

きる作用がある。By inserting a gap material between flat transparent and transparent substrates and fusion welding the gap material even partially to the transparent substrate, there is an effect that all parts of the transparent substrate can be maintained at approximately the same gap size.
以下、実施例により本発明を詳述する。 Hereinafter, the present invention will be explained in detail with reference to Examples.

A low melting point glass film 6.8 consisting of liquid glass is applied;
A gap material 7 made of glass spheres is inserted between both transparent substrates, and a low melting point galan film 6.9 is formed by increasing the temperature while applying pressure to both transparent substrates or by applying ultrasonic pressure welding.

いことは言うまでもない。Incidentally, the transparent plate 1 may be made of plastic, the low melting point glass films 6 and 8 may be made of plastic films, and the gap material 7 may also be made of plastic balls. Furthermore, the gap material 7 may be a low melting point glass sphere. FIG. 2 is a structural diagram of a liquid crystal display showing another embodiment of the present invention, in which tin oxide wiring is provided on the surface of the transparent plate 11.15. 12
．． 14 is formed, and an insulating film 18 made of glass or plastic is formed on the surface thereof to form a transparent substrate, and between the transparent substrates is a small-diameter gap material 19 made of a glass or plastic ball, and a glass or plastic ball. A large-diameter gap material 17 coated with low-melting point glass or plastic is mixed and placed on the surface of the plastic sphere, and the temperature is increased or ultrasonic waves are applied without applying pressure between the transparent substrates. The insulating films 16 and 18 are bonded to each other through adhesive surfaces 20 and the like, and the liquid crystal 13 is filled. The gap material may be made entirely of low melting point materials, and does not necessarily need to be a mixture of large diameter gap material and small diameter gap material, and the large diameter gap material may be made of low melting point material. It doesn't have to be a material,
It goes without saying that the large diameter gap material itself may be made of a low melting point material.

。As in the present invention, by fusion welding the transparent substrate of the liquid crystal display and the gap material, even if only partially, it is possible to obtain a uniform gap interval over the entire surface of the large-diameter liquid crystal display.
As a result, there is an effect that image unevenness does not occur.
