1. An electro-optic device alternately displaying right-eye image and left-eye image, comprising:
a plurality of scanning lines; a plurality of signal lines; a plurality of pixels that are arranged to correspond to intersections between the plurality of scanning lines and the plurality of signal lines; a scanning line driving circuit that sequentially selects first combination of the plurality of scanning lines which being formed by two scanning lines adjacent to each other in a first unit period and sequentially selects second combination of the scanning lines which being formed by two scanning lines and shifted by one scanning line from the first combination in a second unit period, the first unit period and the second unit period being included in a display period in which the right-eye image is displayed and in a display period in which the left-eye image is displayed; a signal line driving circuit that supplies a gray scale potential corresponding to an image signal of a pixel corresponding to one scanning line of the first combination of the plurality of scanning lines in the first unit period and supplies a gray scale potential corresponding to an image signal of a pixel corresponding to other scanning line of the first combination of the plurality of scanning lines in the second unit period; stereoscopic glasses that include right-eye shutter and left-eye shutter; and a glasses control circuit that controls both the right-eye shutter and the left-eye shutter to a light-blocking state in the first unit periods of the display periods of the right-eye and the first unit periods of the display periods of the left-eye image, controls the right-eye shutter and the left-eye shutter to a light-transmission state and the light-blocking state, respectively, in the second unit period of the display period of the right-eye image, and controls the left-eye shutter and right-eye shutter to the light-transmission state and the light-blocking state, respectively, in the second unit period of the display period of the left-eye image; wherein in first control period and second control period alternately repeated, during the first control period when the signal line driving circuit supplies the gray scale potential corresponding to the image signal of the pixel corresponding to one scanning line of the first combination of the plurality of scanning lines in the first unit period and supplies the gray scale potential corresponding to the image signal of the pixel corresponding to other scanning line of the first combination of the plurality of scanning lines in the second unit period, during the second control period when supplies the gray scale potential corresponding to the image signal of the pixel corresponding to other scanning line of the first combination of the plurality of scanning line in the first unit period and supplies the gray scale potential corresponding to the image signal of the pixel corresponding to one scanning line of the first combination of the plurality of scanning line in the second control period, the signal line driving circuit sets the polarity of the gray scale potential with respect to a reference voltage to a first polarity in the first unit period, and the signal line driving circuit sets the polarity of the gray scale potential with respect to the reference voltage to a second polarity reverse to the first polarity in the second unit period. |
