Abstract
PURPOSE: To obtain the liquid crystal display device which is capable of performing bright colored displaying of a wide visual field by using the liquid crystal composition which has smectic A phase and nematic phase and whose dielectric anisotropy is positive as liquid crystal and applying parallel orientation surface treatment to substrats.
CONSTITUTION: Liquid crystal 3 added with dichromatic dyes is held between a pair of transparent substrates 1, 2. Transparent electrodes 4,5 for display are provided on the inside surfaces of the substrates 1, 2 and a transparent conductive film 7 is provided over the entire surface on the outer side of the electrodes and is connected to a heating power source 8. A light scattering plate 9 is installed behind this liquid crystal panel. Parallel orientation surface treatment is applied on the inside surfaces of the substrates 1, 2. The liquid cyrstal 3 used in this device is the liquid crystal composition which exhibits smectic A phase in an ordinary temperature region, has nematic phase in a higher temperature region than for the smectic A phase and whose dielectric anisotropy is positive. The liquid crystal display device obtained in this way is capable of performing bright colored displaying of a wide visual field and has the feature of small power consumption.
