A shift register employs only a thin film transistor of the same type channel and has a level shifter built-in. A shift register with a built in level shifter includes a plurality of stages and a plurality of level shifters. The stages are connected in cascade to shift a start pulse inputted through an input terminal and sequentially output the shifted pulse. The level shifters level-shift a voltage level of the shifted pulse applied from each of the stages and outputting it.

A shift register circuit is provided that is adaptive for reducing a swing width of a clock voltage. In the shift register, a plurality of stages, one for each scanning line, generate first driving signals in response to first and second clock signals. A level shifter is connected between each the stages and its respective scanning line to receive the first driving signal, to thereby apply a second driving signal having a larger swing width than the first driving signal to the scanning line.
