Active-matrix device, electro-optical display device, and electronic apparatus
First Claim
1. An active-matrix device, comprising:
- a substrate;
a plurality of pixel electrodes provided on 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 of the pixel electrodes;
a movable electrode mainly made of silicon and displaceably provided so as to contact with and separate from the fixed electrode; and
a driving electrode provided to oppose the movable electrode via an electrostatic gap;
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;
the movable electrode includes a silicon layer made of monocrystalline silicon; and
the silicon layer is formed by depositing an amorphous silicon film and then annealing the film.
