Abstract

PURPOSE:To elevate contrast without causing a memory phenomenon, by enclosing a cholesteric liquid crystal, etc. between two substrates having a specific gap. CONSTITUTION:An electrode for applying an electric field is placed, a gap (d) between substrates 2 to which processing has been executed so that liquid crystal molecules 1 of the boundary of the substrates 2 are oriented in parallel or almost parallel with the substrates 2 at a low tilt angle is set so that an expression (p denotes a spiral pitch of cholesteric phase; and theta denotes an orientation angle of liquid crystal molecules on the boundary of the opposed substrates, and a radian) is applicable, and between these substrates 2, a cholesteric liquid crystal or a mnematic liquid crystal whose dielectric anisotropy is positive, and a liquid crystal composition having optical activity are enclosed. In this way, it is possible to obtain a guest-host liquid crystal display device which does not cause a memory phenomenon and high in contrast.
