Abstract
PURPOSE: A low-voltage-working, remarkably viewable liquid crystal indicator includes a new sealing material comprising a liquid crystal mixture containing alpha-substituted-trans-stilben, and a dye as a controller.
CONSTITUTION: A liquid crystal indicator comprises a container, a liquid crystal mixture 7 and a dye. The container consists of two base plares 3, 4 having In2 O3 electrodes 1, 2 and edge-sealed members 5, 6. An illustrative mixture 7 comprises a liquid crystal mixture of MBBA and EBBA in a weight ratio of 6:4, mixed with 30 wt% of alpha-substituted-trans-stilben compound of general formula as illustrated, such as 4-ethoxy-hexyloxy-alpha-cyano-trans-stilbene and a dye. The useful dye is, for example, 4-(N-pyrolidinophenly) azo-5'-nitrothiazole. The liquid crystal indicatior works at a lower valtage, as low as one-third of the prior device. It is colorless when no electric field is present and colored by energizing. Even when it is constructed in reflecting-type indicator, it exhibits high viewability due to a remarkable contrast.
