Abstract
In an active-matrix driving type electro-optical apparatus including an increased number of image signal lines corresponding to an increased number of phases obtained by serial-to-parallel conversion, a liquid crystal apparatus includes a liquid crystal layer disposed between two substrates, pixel electrodes formed in a matrix fashion on a substrate, and TFTs serving for switching and controlling the pixel electrodes for suppressing the intrusion of high-frequency clock noise into an image signal. Image signal lines extend on the substrate at both sides of a data line driving circuit. The image signal lines are electrically shielded from clock signal lines, for example, by shielding lines formed on the substrate, and maintained at a constant voltage.
