Abstract

PURPOSE: To attain color display in a colored and black state or in a different colored state, by combining a guest-host type liquid-crystal panel, mutual-transfer type liquid-crystal panel and black or colored light absorptive plate.
CONSTITUTION: The display unit consists of guest-host type liquid crystal 1, mutual-transfer type liquid-crystal panal 2, black or colored light absorptive plate 3, and driver circuit 4 and 5. Panels 1 and 2 are composed of a couple of glass substrates 7 and 11 provided with clear electrodes 6 and 10 of In2O3 or the like, adhesives 8 and 12, and cholesteric liquid crystals 9 and 13 whose dielectric anisotropy is positive, and multi-coloring matter is added to liquid crystal 9. The vertical orientation process of internal surfaces of substrates 7 and 11 is done. In the device of this constitution, a voltage causing light scattering is applied momently to panel 2 without applying no voltage to panel 1, so that panel 1 will be colored. On the other hand, an adequate voltage is applied to panel 1 and a voltage making panel 2 clear is applied momently to panel 2, so that the device will be changed into a black or colored display state. In addition, the power consumption is extremely small.
