Abstract:
The object of the present invention is to make it possible to form an LTPS TFT and an oxide semiconductor TFT on the same substrate. A display device includes a substrate having a display region in which pixels are formed. The pixel includes a first TFT using an oxide semiconductor 109. An oxide film 110 as an insulating material is formed on the oxide semiconductor 109. A gate electrode 111 is formed on the oxide film 110. A first electrode 115 is connected to a drain of the first. TFT via a first through hole formed in the oxide film 110. A second electrode 116 is connected to a source of the first TFT via a second through hole formed in the oxide film 110.
