Abstract

The display device includes: an insulating substrate (215) section that is a substrate having an insulation property; a thin film transistor section (220) in which a thin film transistor is formed in each pixel on the insulating substrate section (215); a shutter mechanism section (300) that is electrically driven by the thin film transistor of the thin film transistor section (200) so as to control light transmission of each pixel (210). The shutter mechanism section (300) has a mechanical layer (352) that is a structural portion and a conductive layer (354) that is formed on the mechanical layer (352) . Both of the mechanical layer (352) and the conductive layer (354) are fixed in direct contact with the conductive portion (226) formed on the thin film transistor section (200).

Description

technical field [0001] The present invention relates to a display device, in particular to a display device in which microelectromechanical systems are applied to pixels. Background technique [0002] Display devices such as liquid crystal display devices are widely used as display devices for information communication terminals such as computers and television receivers. In a liquid crystal display device, an image is displayed by changing the alignment direction of liquid crystal molecules sealed between two substrates of a liquid crystal panel to change the degree of transmission of light irradiated from a backlight to the liquid crystal panel. In recent years, display devices typified by liquid crystal display devices have been used particularly in mobile phones and smartphones. [0003] On the other hand, a structure to which a microfabrication technology called MEMS (Micro Electro Mechanical Systems: Micro Electro Mechanical System) is applied is used in various field...
