Disclosed is a piezoelectric/electrostrictive element composed of an actuator section (12) of a uni-morph type comprising a main actuator element (24) including a piezoelectric/electrostrictive layer (20) and a pair of electrodes (22a, 22b) formed on a first principal surface of the piezoelectric/electrostrictive layer (20); a vibrating section (16) which contacts with a second principal surface of the piezoelectric/electrostrictive layer (20) for supporting the main actuator element (24); and a fixed section (18) for supporting the vibrating section (16) in a vibrative manner; wherein a relationship of y = ax is satisfied, and an expression of 1/10 ≤ a ≤ 100 is satisfied provided that x represents a distance between the pair of electrodes (22a, 22b) (1 µm ≤ x ≤ 200 µm), and y represents a thickness of the piezoelectric/electrostrictive layer (20) (1 µm ≤ y ≤ 100 µm). Accordingly, it is possible to greatly increase the relative displacement amount between the no-voltage-loaded state and the voltage-applied state and the relative displacement amount between the states in which mutually opposite electric fields are applied, making it possible to realize easy control when the element is utilized for actuators and improvement in sensitivity when the element is utilized for sensors.

One selection period S and display cycles Td of a number corresponding to a maximum gradation level are allotted in one field, and the display cycle Td is composed of an unselection period U and a reset period R to perform the following control. A row electrode-driving circuit (202) is used to output a selection pulse Ps during the selection period S, output an unselection signal Su during the unselection period U in the display cycle Td, and output a reset pulse Pr during the reset period R. A column electrode-driving circuit (204) is used to output an ON signal during a light emission maintenance period, and output an OFF signal at least at an end timing of the light emission maintenance period, of the period other than the light emission maintenance period. Accordingly, it is possible to effectively reduce the electric power consumption, and it is possible to achieve the high brightness.

Assuming that a display period for one image is one field, a light source turn on period (Tb) and a light source turn off period (Tc) are set for the one field. An overall bending displacement period (Td) for making bending displacement of all actuator elements (14) is set within the light source turn off period (Tc). A gradational display period (Te) for performing substantial gradational display and a reset period (T R ) for resetting the bending displacement of all of the actuator elements (14) are set within the light source turn on period (Tb). Subfields (SF1 to SFn) of a number corresponding to the maximum gradation level are set within the gradational display period (Te). Timing control is performed so that all row selection is completed within each of the subfields (SF1 to SFn). Accordingly, the gradation level is advantageously extended when a relationship of Tr >> Tf is given between a light-emitting rising time Tr of the picture element and a quenching falling time Tf of the picture element.
