Abstract

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

Claims (25)

1 . A display device comprising:

an insulating substrate that is a substrate having an insulation property; and

a plurality of pixels that forms a display section on the insulating substrate,

wherein each pixel of the plurality of pixels includes:

a thin film transistor;

a shutter mechanism section that is electrically driven by the thin film transistor so as to control light transmission of each pixel; and

a first conductive layer that is formed on the insulating substrate;

wherein the shutter mechanism section includes:

a mechanical layer that is a structural portion; and,

a second conductive layer that is formed on the mechanical layer, and

wherein both of the mechanical layer and the second conductive layer are fixed in direct contact with the first conductive layer.

2 . The display device according to claim 1 ,

wherein the shutter mechanism section includes

a shutter portion that blocks light,

a beam portion that is operable to drive the shutter portion and is a beam-like structure extending in a direction parallel with a substrate surface of the insulating substrate, and

an anchor portion that anchors and supports the beam portion,

wherein each of the shutter portion, the beam portion and the anchor portion has the mechanical layer and the second conductive layer, and

wherein the mechanical layer and the second conductive layer of the anchor portion are fixed in direct contact with the first conductive layer.

3 . The display device according to claim 2 ,

wherein the anchor portion has a bowl shape, and

wherein the second conductive layer is formed around the outside of the bowl shape of the mechanical layer.

4 . The display device according to claim 3 , wherein the second conductive layer is also formed inside the bowl shape of the mechanical layer.

5 . The display device according to claim 2 ,

wherein the anchor portion has a bowl shape, and

wherein the mechanical layer is formed around the outside of the bowl shape of the second conductive layer, and is also formed inside the bowl shape of the second conductive layer.
