The invention allows stable fabrication of a TFT circuit board used in a display device and having thereon an oxide semiconductor TFT. A TFT circuit board includes a TFT that includes an oxide semiconductor. The TFT has a gate insulating film formed on part of the oxide semiconductor and a gate electrode formed on the gate insulating film. A portion of the oxide semiconductor that is covered with the gate electrodeand a portion of the oxide semiconductor that is not covered with the gate electrode are both covered with a first interlayer insulating film. The first interlayer insulating film is covered with a first film, and the first film is covered with a first AlO film.

TFT circuit board and display device having the same

A display device includes an electrode layer formed at a predetermined position on a substrate, an insulating film having a through-hole formed on the top of the electrode layer, and a wiring film connected to the electrode layer via the through-hole formed in the insulating film. Based on a surface of the substrate, the through-hole includes a first taper portion having a first taper angle, a second taper portion formed higher than the first taper portion and having a second taper angle different from the first taper angle, and a third taper portion formed higher than the second taper portion and having a third taper angle different from the second taper angle.

Display device and method for manufacturing display device

The MEMS shutter includes a shutter having an aperture part, a first spring connected to the shutter, a first anchor connected to the first spring, a second spring and a second anchor connected to the second spring, an insulation film on a surface of the shutter, the first spring, the second spring, the first anchor and the second anchor, the surfaces being in a perpendicular direction to a surface of a substrate, and the insulation film is not present on a surface of the plurality of terminals, and a surface of the shutter, the first spring, the second spring, the first anchor and the second anchor, the surfaces being in a parallel direction to a surface of the substrate and on the opposite side of the side facing the substrate.
