Abstract
Picture display cell, method of forming an orientation layer on a substrate of the picture display cell and monomeric compounds for use in the orientation layer. The picture display cell comprising two transparent plates having an electrode with thereon an orientation layer and a sealing ring between the ends of the plates, a liquid crystalline material being present in the space between the plates and the ring, the orientation layer being formed from a monomer or a low molecular compound which is first oriented in a field.
Claims12
A picture display cell comprising as a substrate two oppositely located plates which are transparent to light and which on the facing sides comprise an electrode of a material which is transparent to light having thereon an orientation layer and a sealing ring between the ends of the plate, a liquid crystalline material being provided in the space between the plates and the ring, characterized in that the orientation layer is formed from a monomer or a low molecular weight compound which is first oriented at a given angle essentially only in an electric or magnetic field and is then polymerized.
A method of forming an orientation layer on a substrate for a picture display cell comprising an electrode, characterized in that a film of a liquid crystalline monomer is provided in the substrate, the monomer is oriented essentially in a magnetic or electric field at a given angle, and is then polymerized.
