Dimensional accuracy and uniformity of substrate gaps have become more required than ever before. Even with the conventional control method using beads, it is possible to respond to substrate gaps with high precision by dispersing more beads. However, beads have the property of scattering light in liquid crystal, and by increasing the amount of beads, even in the mode where light is blocked, there is light leakage due to diffuse reflection from the beads, which causes deterioration of image quality such as contrast. It has become.

板に該当する平滑性を有し、液晶への問題は全くない。Function> The columnar convex portion made of ultraviolet curable resin whose bottom is formed by a molded wall made of polished glass serves as a spacer to control the gap between the substrates when bonding two glass substrates together. Also,
Since the molded wall is made of polished glass, the resin surface of the flat part has a smoothness corresponding to that of the substrate, and there is no problem with the liquid crystal.
従来のビーズが画素面上全域に散布されていたのに対し

。Moreover, when using this invention, after forming the spacer, the IT
Formation of the O film requires patterning and orientation treatment, but sputtering is used for film attachment, offset printing is used for patterning, and conventional methods can be used for orientation. Since the resist film is printed with a blanket cylinder, the difference in height in units of cubic meters is not a problem, and the same is true in the alignment process.
