Abstract
Narrowing of a picture-frame of a display device that can perform switching between vertical scanning directions is implemented. A gate driver () includes a shift register () including a plurality of unit circuits including n unit circuits connected to write control lines; a first scanning order switching circuit () including a plurality of first switching circuits respectively corresponding to the plurality of unit circuits; and a second scanning order switching circuit () including n second switching circuits connected to initialization control lines. The first scanning order switching circuit () controls operation of the shift register () based on scanning order instruction signals. Each second switching circuit applies, based on the scanning order instruction signals, an output signal from a unit circuit on a previous stage side or an output signal from a unit circuit on a subsequent stage side, as a second scanning signal, to an initialization control line.
