<P>PROBLEM TO BE SOLVED: To attain a liquid crystal element for suppressing thickness variation in the liquid crystal layer due to temperature increase, using a simple configuration. <P>SOLUTION: The liquid crystal element arranges a first transparent substrate 11A, a first transparent electrode 12A, the liquid crystal layer 13, a second transparent electrode 12B, and a second transparent substrate 11B, in this order. The liquid crystal layer 13 has 1×10<SP>-5</SP>/°C to 7×10<SP>-4</SP>/°C of the linear expansion coefficient. Herein, the liquid crystal layer 13 may be formed of a side-chain polymer liquid crystal. In addition, a reflecting mirror may be provided on a plane in between the first transparent substrate 11A which includes the surface and the liquid crystal layer 13 and a plane in between the second transparent substrate 11B which includes the surface and the liquid crystal layer 13. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
