Patent ID: 8405644

Claim:
An electro-optical device comprising: a plurality of scan lines; a plurality of data lines; a plurality of pixels respectively provided at intersections between the plurality of scan lines and the plurality of data lines; and a scan line drive circuit that applies a selection voltage to the scan lines in a predetermined sequence, the scan line drive circuit including: (a) a first scan line drive circuit: (i) disposed at one side of the scan line; (ii) being configured to apply the selection voltage to some of the scan lines; (iii) being configured to control a first shift pulse to change from a first direction to a second direction; and (iv) including shift registers with a reset/set type flip flop provided corresponding to the some of the scan lines, each of the reset/set type flip flops including a set terminal and a reset terminal; and (b) a second scan line drive circuit: (i) disposed at the other side of the scan line; (ii) being configured to apply the selection voltage to the remaining scan lines; (iii) being configured to control a second shift pulse to change from a third direction to a fourth direction; and (iv) including shift registers with a reset/set type flip flop provided corresponding to the remaining scan lines, each of the reset/set type flip flops including a set terminal and a reset terminal, wherein the set terminal functions as the reset terminal and the reset terminal functions as a set terminal for each of the reset/set type flip flops when a scanning direction switching signal changes, the changing of the set and reset terminals causes the first shift pulse to change to the second direction, and the changing of the set and reset terminals causes the second shift pulse to change to the fourth direction.
