ABSTRACT:
A liquid crystal display device comprises a pair of substrates, a transparent electrode formed on each of the substrates, an orientation film covering the transparent electrode and a liquid crystal sealedly sandwiched between the pair of substrates, wherein the orientation film comprises a polyimide which is formed by a condensation polymerization of 2,2-bis[4-(4-aminophenoxy)phenyl]propane as an amine component and 1,2,4,5-benzenetetracarboxylic dianhydride as an carboxylic acid component, and is subjected to a uniaxial orientation treatment, and the liquid crystal has a smectic layer structure with its bending direction which is aligned with the direction of the uniaxial orientation treatment.
