ABSTRACT:
A first electrode layer12, a first piezoelectric film layer13, a second electrode layer14, a second piezoelectric film layer15, and a third electrode layer16are layered in that order on a substrate11; these are constrained so as pot to expand or contract in a thickness direction and a piezoelectric transducer is constructed thereby. A plurality of gate lines201and202, a plurality of data lines203and204intersecting with the gate lines, and thin film transistors205and207, disposed at the intersections of the abovementioned gate lines and data lines, are established; one source-drain of the abovementioned thin film transistors is connected to the abovementioned data lines; another source-drain of the abovementioned thin film transistors is connected to the input sides of the abovementioned thin film piezoelectric transducers208through210; the output sides of the abovementioned thin film piezoelectric transducers are connected to the electrodes of electrophoretic ink display elements; and an electrophoretic ink display apparatus is constructed thereby.
