Claim:
1. An electro-optical apparatus comprising: a plurality of scanning lines; a plurality of signal lines; pixels that are disposed to correspond to the intersections of the plurality of scanning lines and the plurality of signal lines, respectively; and a drive unit that supplies drive signals to the plurality of scanning lines and the plurality of signal lines, wherein the plurality of signal lines are divided into k signal line groups corresponding to k image sequence lines (k is an integer of two or greater), wherein the drive unit includes a precharging circuit that supplies precharging signals to the plurality of signal lines, and an image signal circuit that supplies image signals to the plurality of signal lines, wherein the image signal circuit includes k groups of switches which are electronically connected to the k signal line groups and the k image sequence lines, wherein the precharging circuit includes k groups of precharging switches which are electrically connected to the k signal line groups and k precharging sequence lines, wherein when supplying image signals to the k signal line groups in a horizontal scanning period, the drive unit supplies precharging signals to a part of the k signal line groups, and then supplies the image signals thereto, and in contrast, supplies the image signals to the remainder of the k signal line groups without supplying the precharging signals thereto, wherein in a first horizontal scanning period, the drive unit supplies the precharging signals to the part of the k signal line groups, and then supplies the image signals thereto, and in contrast, supplies the image signals to the remainder of the k signal line groups without supplying the precharging signals thereto, and wherein in a second horizontal scanning period subsequent to the first horizontal scanning period, the drive unit supplies the precharging signals to the part of the k signal line groups, and then supplies the image signals thereto, and in contrast, supplies the image signals to the remainder of the k signal line groups without supplying the precharging signals thereto, and wherein the signal lines to which the precharging signals are supplied are different between the first horizontal scanning period and the second horizontal scanning period.
