PROBLEM TO BE SOLVED: To provide an optical mirror 20 capable of being formed into a desired shape with a simple configuration.SOLUTION: In a head-up display 1, an optical mirror 20 includes: an electrolyte layer 30; a one-side electrode 31 formed in a thin film over entire side of one side 30a of the electrolyte layer 30 along the side of the one side 30a; and opposite-side electrodes 32-35, each of which independently formed in a thin film, along a side of an opposite side 30b of the electrolyte layer 30. A voltage is applied between the one-side electrode 31 and each of the opposite-side electrodes 32-35 from a control circuit 40, respectively, thereby the electrolyte layer 30 is bent for each of the opposite-side electrodes. Accordingly, an optical mirror 20 can be formed in a desired shape, without providing a plurality of electrodes by patterning on the side of the one side 30a of the electrolyte layer 30. |
