Problems solved by technology

[0007] However, in such an active matrix device, when the cantilever beam is brought into contact with the pixel electrode, there is a problem of contact and adhesion between the cantilever beam and the driving electrode.
Therefore, such active matrix devices have low reliability

Abstract

An active matrix device (10) includes: a plurality of pixel electrodes (8) provided above a surface of the substrate (50); a plurality of switching elements (1) provided so as to correspond to the pixel electrodes, each switching element (1) including: a fixed electrode (3) coupled to one of the pixel electrodes (8); a movable electrode (5) provided so as to come into contact with or depart from the fixed electrode (3); and a drive electrode (2) provided so as to be opposed to the movable electrode (5) with an electrostatic gap therebetween; a plurality of first wiring lines (11) coupled to the movable electrodes (5); and a plurality of second wiring lines (12) coupled to the drive electrodes (2). At least space between the movable electrode and the drive electrode of each of the switching elements is filled with liquid crystal.

Description

technical field [0001] The invention relates to an active matrix device, a photoelectric display device and electronic equipment. Background technique [0002] For example, an LCD (Liquid Crystal Display: liquid crystal display) panel adopting an active matrix driving method includes a plurality of pixel electrodes, switching elements provided corresponding to the pixel electrodes, and wiring connected to each switching element. Active matrix device (for example, refer to Patent Document 1). [0003] Generally, TFTs are used as switching elements in active matrix devices. Although TFT uses a-Si thin film or p-Si thin film as its semiconductor layer, since these thin films are photoconductive, light leakage may occur when light enters, and the cut-off (OFF) resistance of TFT may decrease, or The problem of threshold shift of TFT. [0004] To solve the problem of light leakage as described above, a method of providing a light-shielding layer such as a black matrix for shiel...
