Abstract
An electro-optical apparatus is capable of displaying an high-quality image including no non-uniformity in contrast even when the scanning direction is inverted. A precharging circuit driving signal line and a precharging signal line are formed on a TFT array substrate such that they extend around a data line driving circuit and a pixel area and such that these signal lines are connected to a precharging circuit from two sides of the precharging circuit. Signal supplying contacts for making connection to external signal sources are also formed on the substrate. Two ends of the precharging circuit driving signal line are connected to signal supplying contacts and, respectively, and two ends of the precharging signal line are connected to the other signal supplying contacts, respectively, so that the precharging circuit driving signal and the precharging signal are supplied from two sides.
