Abstract
PURPOSE: To enable to perform color display with colored state, and black or other colored state, by controlling the voltage fed to the guest host type liquid crystal panel and the phase transfer type liquid crystal panel.
CONSTITUTION: When suitable voltage is applied to the guest host type liquid crystal panel 1 and the phase transfer type liquid crystal panel 2 with drive circuits 4 and 5, since the both panels 1, 2 are non-colored and transparent, the observer 14 can see the color of the photo absorption plate, that is, black or colored state for the display surface. Further, when the applied voltage is O to the both panels 1 and 2, since the panel 1 is colored state due to photo absorption of color element and the panel 2 is in photo scattered state, the observer 14 can see the coloring of the guest host type liquid crystal panel 1 on the display surface. Thus, the color display with colored state, black or other color state can be made.
