Patent ID: 7952041

Claim:
An active-matrix device, comprising: a substrate; a plurality of pixel electrodes provided above a first surface of the substrate; a plurality of switching elements provided to correspond to each of the pixel electrodes, each of the switching elements including: a fixed electrode connected to each pixel electrode; a movable electrode displaceably provided to contact with and separate from the fixed electrode; a driving electrode provided to oppose the movable electrode via an electrostatic gap; and an adhesion-preventing mechanism that prevents adhesion between the movable electrode and the driving electrode; a first wiring connected to the movable electrode; and a second wiring connected to the driving electrode, wherein a voltage is applied between the movable electrode and the driving electrode to generate an electrostatic attraction between the movable electrode and the driving electrode so as to displace the movable electrode such that the movable electrode contacts with the fixed electrode to electrically connect the first wiring to the pixel electrode; and wherein the pixel electrodes are located in positions different from and above those of the switching elements in a thickness direction of the substrate, each pixel electrode is arranged so as to overlap the switching element that corresponds to the pixel electrode when two-dimensionally viewed, and each pixel electrode includes a plurality of apertures.
