Abstract

PURPOSE: To time-dividedly drive a White-Taylor type guest-host liquid crystal display device without decreasing the contrast by applying a horizontal orientation treatment to upper and lower substrates and specifying the concn. of an optical activating agent to be added to a liquid crystal.
CONSTITUTION: Substrates 1, 11 provided with transparent electrodes 2, 12 are adhered by a sealing material 3 as a spacer to form a liquid crystal display device. An orienting agent is coated on these upper, lower substrates 1, 11, and desired horizontal orientation treatment is applied. A nematic liquid crystal is used as a host liquid crystal, and the liquid crystal mixture consisting in containing a dichromatic dye 5 of a blue system or the like into a chiral nematic liquid crystal 4 prepd. by adding an optical activating agent to said liquid crystal is prepared and is injected into the liquid crystal display device. The concn. C of the optical activating agent in this liquid crystal mixture is set at 7P0/8d≤C≤P0/d (P0: the intrinsic spiral pitch of the liquid crystal, d: the distance between the substrates). The time- divided driving by a voltage averaging method is accomplished under low voltage by this device.
