Title:
半導体装置
Document Type and Number:
Japanese Patent JP5667610
Kind Code:
B2
Abstract:
A highly reliable display device which has high aperture ratio and includes a transistor with stable electrical characteristics is manufactured. The display device includes a driver circuit portion and a display portion over the same substrate. The driver circuit portion includes a driver circuit transistor and a driver circuit wiring. A source electrode and a drain electrode of the driver circuit transistor are formed using a metal. A channel layer of the driver circuit transistor is formed using an oxide semiconductor. The driver circuit wiring is formed using a metal. The display portion includes a pixel transistor and a display portion wiring. A source electrode and a drain electrode of the pixel transistor are formed using a transparent oxide conductor. A semiconductor layer of the pixel transistor is formed using the oxide semiconductor. The display portion wiring is formed using a transparent oxide conductor.
