Method of orienting liquid crystal of liquid crystal display medium and apparatus for carrying out the same

Abstract

A liquid crystal orienting method orients a liquid crystal of a liquid crystal display medium (1) having a base (2), a conductive layer (3) formed on the base (2), and a polymer dispersed liquid crystal film (PDLC film) (4) formed of a material prepared by dispersing the liquid crystal in a polymer. A charger (71) is disposed opposite to the surface of the liquid crystal display medium (1) on the side of the PDLC film (4) so as not to come into contact with the liquid crystal display medium (1), and a grounded electrode (72) is disposed near the charger (71) so as to come into contact with the liquid crystal display medium (1). A potential difference is created through the conductive layer (3) between a portion of the liquid crystal display medium (1) charged by the charger (71) and a portion of the same in contact with the electrode (72) by electrostatic induction. Consequently, a vertical electric field is applied to the PDLC film (4) to orient the liquid crystal of the PDLC film (4). The surface of the liquid crystal display medium (1) is covered with a nonconductive layer (5).
