Abstract
PURPOSE: To enable to color display with color, black color or separate color, by constituting the guest and host type liquid crystal panel and DSM type liquid crystal panel that one is fed with a voltage with another not applied.
CONSTITUTION: When no voltage is applied to the guest host type liquid crystal panel 1 and a voltage is fed to the DSM type liquid crystal panel 2 with the drive circuit 5, since the panel 1 is in colored state and the panel 2 is in photo scattered state, the observer can see the color by the coloring of the liquid crystal panel 1. On the other hand, when a voltage is fed to the guest host type liquid crystal panel 1 with the drive circuit 4 and it is made to non-color transparent state, and when no voltate is applied to the panel 2 and it is also in non-colored state, the observer 14 can see the display surface as black or other color by the photo absorption plate 3. Thus, the color display by color, black color or other color can be performed.
