Abstract
PURPOSE: To obtain bright display in a plural-layers liquid crystal display device by using the liquid crystal with 2-color effect for one component and more in mixed liquid crystals, making the orientation of liquid crystal of each layer parallel to the plate in either status of display or clear and making the direction of each chamber cross at right angle each other.
CONSTITUTION: For example, 2-layers liquid crystal display device is constituted by transparent plates 1 and 3 to which transparent electrodes 4 and 6 are provided and substrate 2 whose both surfaces are fixed to transparent electrode 5. One or more kinds of azo or azoxy liquid crystals with 2-color effect are used for liquid crystals 7 and 8. The long axis of liquid crystal molecules in liquid crystals 7 and 8 is made perpendicular to plates 1W3 when electric field is not applied, and when electric field is applied, plates 1W3 are oriented so that the long axis is parallel to plates 1W3 and liquid crystals 7' and 8' cross at right angle each other. N type liquid crystal is used for the liquid crystal in this case. When the liquid crystal is made parallel to the plates in case when electric field is not applied, P type liquid crystal is used. Thus, bright and high contrast display can be obtained without a deflection plate.
