Title: Manufacture of liquid crystal display device
Inventor: ONO YOICHI
IPC: G02F1/133
Filed: 1986-06-19
Abstract: PURPOSE:To uniformly orient liquid crystal molecules at a large angle at low cost by forming an oriented layer by a process where liquid crystal molecules are oriented vertically, a process where an oriented layer is laminated on another oriented layer, and a process where the laminate layer is rubbed. CONSTITUTION:The process for forming the oriented layer by arraying liquid crystal molecules in one direction consists of at least the vertical orienting process in which liquid crystal molecules are arrayed perpendicular to the surface of a substrate to be treated, a process in which a treatment is performed on the oriented layer by using an orienting agent having a lower molecular weight than the orienting agent used for the vertical orientation treatment, and the process in which the treated surface is rubbed in one direction. Consequently, a uniform layer which has a specific tilt angle and specific directivity is formed on the surface of the surface, so the tilt angle of the liquid crystal molecules is controllable to 0-60 deg. and even when the twist angle of the liquid crystal molecules is set to >=60 deg., stable orientation is performed.
