When a 2D display is performed, a controller causes a first selection signal to be in an active state during a given period, and causes a second selection signal to be in the active state during another given period after causing the first selection signal to be in a non-active state. When a 3D display is performed, the controller causes the first selection signal to be in the active state at a given timing point, cause the second selection signal to be in the active state during a period when the first selection signal is in the active state, and thereby cause an overlapping period to arise during a period which is part of a selection period for selecting signal lines corresponding to the first selection signal, and which is part of another selection period for selecting signal lines corresponding to the second selection signal. |

1. An electro-optic device comprising:
a plurality of scanning lines; a plurality of signal lines; a plurality of pixels each provided so as to correspond to one of intersections of the plurality of scanning lines and the plurality of signal lines; a scanning line driving portion configured to perform scanning line driving operations each for selecting at least one of the scanning lines at a corresponding timing point in accordance with a vertical scanning frequency; a signal line driving portion configured to supply the pixels, via the signal lines, with image signals each including at least time-division multiplexed data voltages each having a magnitude equivalent to a gray-scale level with which display is to be performed; a signal line selection portion configured to perform signal selection operations in accordance with a control signal, each for selecting at least one signal line which is included in the signal lines, and through each of which a corresponding one of the image signals is supplied; and a controller that performs control so as to cause the vertical scanning frequency to be switched to any one of a first frequency and a second frequency which is higher than the first frequency, wherein the controller is configured to, in a state subsequent to switching of the vertical scanning frequency to the first frequency, output the control signal so as to, after an end of a first selection period for selecting at least one of the signal lines, cause any other at least one of the signal lines to be selected, and, in a state subsequent to switching of the vertical scanning frequency to the second frequency, output the control signal so as to, during a second selection period for selecting at least one of the signal lines, cause any other at least one of the signal lines to be selected, and thereby cause an overlapping period to arise during part of the second selection period for selecting at least one of the signal lines. |
