Claims

[Claims for Utility Model Registration] 1. A transparent layer having optical anisotropy is interposed between polarizing plates having polarization axes in a fixed direction, and the polarizing plates are arranged facing each other so as to be relatively rotatable. 1. A colorable light receiving device characterized in that the crossing angle of polarization axes between the polarization axes can be controlled. 2. The device according to claim 1, wherein the polarizing plate is a polarizing film. 3. The device according to claim 1, wherein a transparent layer having optical anisotropy is attached to a polarizing plate, and the transparent layer is interposed between the polarizing plates. 4. The device according to claim 1, in which the transparent layer is made of a birefringent medium. 5. The device according to claim 1 of the utility model registration, which enables continuous change of color by continuously changing the crossing angle of the polarization axes.
