Abstract:
Disclosed is a display device including a transistor showing extremely low off current. In order to reduce the off current, a semiconductor material whose band gap is greater than that of a silicon semiconductor is used for forming a transistor, and the concentration of an impurity which serves as a carrier donor of the semiconductor material is reduced. Specifically, an oxide semiconductor whose band gap is greater than or equal to 2 eV, preferably greater than or equal to 2.5 eV, more preferably greater than or equal to 3 eV is used for a semiconductor layer of a transistor, and the concentration of an impurity which serves as a carrier donor included is reduced. Consequently, the off current of the transistor per micrometer in channel width can be reduced to lower than 10 zA/μm at room temperature and lower than 100 zA/μm at 85° C.

Claim (Index 11):
A display device comprising:\n a transistor; and a pixel electrode electrically connected to the transistor, wherein the transistor comprises:\n a semiconductor film comprising a channel formation region; \n a source electrode electrically connected to the semiconductor film; and \n a drain electrode electrically connected to the semiconductor film; \n a gate electrode; and \n a gate insulating film between the semiconductor film and the gate electrode \n wherein the transistor has a characteristic that a current flowing between the source electrode and the drain electrode is lower than 10 zA/\u03bcm at room temperature when a voltage of 3.1 V is applied between the source electrode and the drain electrode, wherein the current is normalized by a channel width of the transistor, and wherein the semiconductor film is an oxide comprising indium and zinc.
