ABSTRACT:
A liquid crystal device is constituted by disposing a liquid crystal between a pair of substrates each having an electrode thereon and coated with a polymeric ion-conductive film and an organic electroconductive alignment film in this order or in reverse order. The alignment film may be provided with an electroconductivity selectively at parts thereof above the electrode so as to suppress occurrence of crosstalk between pixels. The above arrangements of the ion-conductive film and the alignment film are suitable for providing a practical liquid crystal device affording a high contrast and a moderate V-T characteristic advantageous for halftone display.
