Abstract

PURPOSE: To enhance the contrast and remove defects due to deflecting mirror surface, by mixing cholesteric liquid crystal to nematic liquid crystal, and adding fluorescent pigment into this mixture.
CONSTITUTION: A liquid crystal composition 5 obtained by heating and dissolving and mixing nematic liquid crystal, cholesteric liquid crystal and fluorescent pigment by the rate of 94.5:5:0.5 is injected into a cell. The reflected light 9 of incident light 7 is slightly colored, but when a voltage is applied from transparent electrodes 3, 4, the reflected light 8 shows a clear color fluorescence. The applied part, when the voltage is removed, has a memory property, and when a higher voltage is applied, the applied part shows the same color tone as non-applied part. Thus, such defect that the reflected light 8 from a reflecting coating mirror plane 6 cannot be distinguished due to existence of white object on the observer's side because of the reflection thereof may be eliminated.
