Filed: 1987-12-02
Abstract: PURPOSE:To enable uniform orientation of a large area by using the side surface of uniaxially orientable polyimide patterned by a photolithographic stage as an epitaxy source for the purpose of liquid crystal orientation. CONSTITUTION:The polyimide film is widely used as the oriented film of a liquid crystal display element such as TN element for which a nematic liquid crystal is used. This film is known to be capable of uniaxially orienting the liquid crystal when shearing stress is applied to the film. The liquid crystal is considered to be oriented along the uniaxially oriented high-polymer chain on the surface of the polyimide film. The polyimide in combination with a photoresist or alone in the case of having a photosensitive group within the molecule can be patterned at necessary spacings exactly in required positions by the photolithographic stage. The uniaxially orientability is, thereupon, imparted to the side surface of the patterns formed by the photolithographic stage and such film is used as the epitaxy source. The uniformly oriented ferroelectric smectic liquid crystal display element having the large area is thereby produced.
