ネルが構成されている。FIG. 2 shows a cross-sectional view of a conventional liquid crystal display device having a vertical alignment film. In FIG. 2, the substrate l is made of glass;
A transparent electrode 2 made of ITO is formed on its upper surface. Furthermore, a vertical alignment film 3 made of a silane camping agent having a long-chain alkyl is formed on top of the film by spin coating, thereby forming a first panel. Similarly, an electrode 5 is placed on the substrate 4.
．． A vertical alignment film 6 is formed as a second panel, and alignment films 3 and 6 are formed.
The first panel and the second panel are bonded together with a sealant 7 while facing each other. A liquid crystal display panel as shown in FIG. 2 is constructed by injecting liquid crystal 8 into the gap between the two panels bonded together.

る場合があった。また、垂直配向剤は、ぬれ性が悪く、
印刷による配向膜形成は困難である。In the method for manufacturing a liquid crystal display device explained with reference to FIG. 2, a vertical alignment agent is formed on a glass substrate by spin coating, and then a sealant is directly formed thereon. It is common to form a sealant after applying the alignment agent, but if this sequence of steps is used, the sealant is likely to be repelled due to the properties of the vertical alignment agent, reducing the adhesion between the alignment film surface and the sealant. However, this may cause peeling or liquid crystal leakage. In addition, vertical alignment agents have poor wettability,
It is difficult to form an alignment film by printing.
そこで本発明は、従来のような基板のはがれや液晶漏れ
等を、配向剤塗布前に一対の両ガラス基板上にシール剤
を形成させることをなくし、簡便な工程で基板とシール
剤の接着性を高められるものである。Therefore, the present invention eliminates the conventional problems such as substrate peeling and liquid crystal leakage by eliminating the need to form a sealant on both glass substrates before applying an alignment agent, and improves the adhesion between the substrate and sealant through a simple process. It is something that can increase the.
