摘要： In a display device including pixel circuits including oxide TFTs, degradation in display quality caused by light irradiation onto the oxide TFTs is suppressed. A TFT having a channel region formed of silicon is adopted as a drive transistor. A TFT having a gate electrode; a first conductive electrode and a second conductive electrode that function as a drain electrode and a source electrode; a back-gate electrode; and a channel region formed of an oxide semiconductor is adopted as a threshold voltage compensation transistor. A second conductive electrode of the drive transistor is connected to the first conductive electrode of the threshold voltage compensation transistor, and a gate electrode of the drive transistor is connected to the second conductive electrode of the threshold voltage compensation transistor. Silicon connected to the second conductive electrode of the drive transistor is used as the back-gate electrode of the threshold voltage compensation transistor.
