ABSTRACT:
A scan-driving circuit capable of increasing image quality and decreasing power consumption, a display device using the scan-driving circuit, an electro-optical device, and a scanning drive method. The scan-driving circuit includes a shift register, level shifter, and scan line drive circuit. The shift register sequentially shifts an enable input/output signal EIO. The enable input/output signal EIO shifted to a block set for a non-display area is bypassed by block select data set in units of blocks divided for a given number of scan lines. The scan lines in the block set for a display area are driven by the shifted enable input-output signal EIO. The scan lines in the block set for the non-display area are driven by a common electrode voltage polarization inversion signal VCOM and a write enable signal WEN.
