Abstract
An electro-optical apparatus is provided which corrects a voltage applied to a pixel with high accuracy. An electro-optical apparatus includes a correction circuit. When, for example, a positive-polarity selection voltage +VS is applied to a scanning line during the second-half period of one horizontal scanning period, the correction circuit detects a spike resulting from voltage switching from a voltage −VD/2 to a voltage +VD/2 on the data lines, determines whether the level of the detected spike is a threshold level or more, and if a determination is made that the level of the detected spike is the threshold level or more, adds a pulse with the same polarity as that of the detected spike to a selection-voltage supply line in the second-half period following the first-half period.
