Title:
LIQUID CRYSTAL DISPLAY CONTAINING ORIENTED FILM AND ITS PRODUCTION
Document Type and Number:
Japanese Patent JP3121099
Kind Code:
B2
Abstract:

PURPOSE: To simply obtain an oriented film of an active display device by arranging a mixture of an reactive and a non-reactive liquid crystal material in contact with the surface of a mold having orientation effect and curing the reactive liquid crystal material.
CONSTITUTION: The surface of the mold in contact with the oriented film to be formed is flat and has the orientation effect, the oriented film is formed from the mixture of the reactive liquid crystal material with the non-reactive liquid crystal material and the reactive liquid crystal material is cured in an oriented state. The surface of the mold having orientation effect is composed of a rubbed polymer film and the film of a polymer to be usually used, such as a polyethylene, or a polyimide is preferable for the purpose and the film is rubbed for example, with a non-fluffy cotton. cloth. The reactive liquid crystal material is advantageously cured for example by using ultraviolet ray, electron beam, X-ray, γ-ray or actinic radiation of a high energy particle to fix the orientation of the molecule in the oriented film by the effective and rapid method in this way.
