Abstract:
1. An electro-optic device comprising: a plurality of pixels which is disposed in correspondence with intersections of a plurality of scanning lines and a plurality of signal lines and which displays gray scales corresponding to potentials of the signal lines when the scanning lines are selected; a scanning line driving circuit which selects the plurality of scanning lines sequentially during respective select periods including a writing period; a signal supply circuit which supplies, to a control line, a control signal which is set so as to have a precharge potential during a precharge period before start of the writing period and which is set so as to have a gray scale potential corresponding to a designated gray scale of each pixel in a time division manner during the writing period; a plurality of switches which controls connection between the plurality of signals and the control signal; and a control circuit which controls the plurality of switches so as to be concurrently turned on during the precharge period and controls the plurality of switches so as to be turned on sequentially during a plurality of unit periods of the writing period, wherein the control circuit sets an initial unit period of the writing period after elapse of the precharge period among the plurality of unit periods so as to be longer than each of the other unit periods such that the gray scale potential is supplied for a longer period of time in the initial unit period than in each of the other unit periods, wherein the signal supply circuit sets the precharge potential of the control signal as a first polarity potential with respect to a reference potential, sets the gray scale potential of the control signal as the first polarity potential during the writing period of a first select period, and sets the gray scale potential of the control signal as a reverse polarity potential to the first polarity potential during the writing period of a second select period, wherein the initial unit period of the writing period of the second select period is longer than the initial unit period of the writing period of the first select periods.
