Abstract
Provided herein are a display apparatus with a touch panel to which a piezoelectric actuator may readily be mounted, and a piezoelectric actuator used in such a display apparatus with a touch panel. A support structure for supporting a piezoelectric actuator 3 on a front surface of a circuit substrate 5 is constituted from a pair of electrically conductive support members 13A, 13B which are each formed of an electrically conductive foam. The piezoelectric actuator 3 may be mounted by locating the piezoelectric actuator 3 with the pair of electrically conductive support members 13A, 13B attached thereto in a predetermined position on the circuit substrate 5, and connecting the pair of electrically conductive support members 13A, 13B to the pair of output electrodes 5A, 5B of the circuit substrate 5.
