Abstract
PURPOSE: To obtain a display element which has superior transmittance and does not cause any blurr by constituting the liquid crystal orientation films to be provided on the substrates formed with electrodes with the polyimide-siloxane copolymer having the unit structure expressed by the specific general formulas.
CONSTITUTION: The liquid crystal orientation film to be provided on the substrates formed with electrodes is constituted by the polyimide-siloxane copolymer having the unit structure expressed by the general formulas (I), (II). For example, 4,4'-bis (m-aminophenoxy) diphenyl sulfone (95mol%), the siloxane compound expressed by the general formula (III) (5mol%), 3,3', 4,4'-benzophenone tetracarboxylic acid dianhydride (100mol%) and N-methyl-2-pyrrolidone are stirred at 15W20°C, whereby a 15% copolymer soln. is obtained. This soln. is diluted to 3% to a polymer soln. for forming orientation films and the thus prepd. soln. is coated to form orientation films of 800Å thickness, after which the circumferences of the substrates are sealed by glass frit and a liquid crystal is injected and sealed, whereby the liquid crystal element is made.
