Abstract
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.
