PROBLEM TO BE SOLVED: To provide an information display device capable of moving and operating a movable plate easily and quickly, an analog electronic watch, and a piezoelectric actuator.SOLUTION: An information display device includes: an indicator panel having an opening; a pair of piezoelectric elements that extend by application of a predetermined voltage and each of whose one end displaces; a moving member that moves in response to the displacement of each one end from a position in contact with one end of one piezoelectric element to a position in contact with one end of the other piezoelectric element; moving member stop means for maintaining a contact condition of the moving member with either the pair of piezoelectric elements; an indicator whose exposure state from the opening is switched in response to moving of the moving member; and display control means for controlling the application of the predetermined voltage. |
