ABSTRACT:
A scan-driving circuit for making a high image quality and a low power consumption compatible. This scan-driving circuit comprises: a shift register including first to Nth flip-flops corresponding to first to Nth scan lines, respectively, and connected in series; a level conversion section including first to Nth level shifter circuits for shifting the voltage levels of the individual output nodes of the first to Nth flip-flops individually; and a scan line drive section including first to Nth drive circuits for driving the first to Nth scan lines sequentially in a manner to correspond to the potentials of the output nodes of the first to Nth level shifter circuits. The first to Nth scan lines are divided into a plurality of blocks, for which the scan lines are individually arranged. The first to Nth drive circuits scan and drive the scan lines in the designated block at a time of a partial display in which the display and drive are done on a block basis.
