Abstract
First and second substrates are disposed facing each other. Drive wiring lines including signal and control lines are formed on the first substrate on the side facing the second substrate. A pixel electrode is formed on the first substrate in the pixel region and on the side facing the second substrate. A switching element is provided for each pixel electrode. A common electrode is formed on the second substrate on the side facing the first substrate. A liquid crystal layer is sandwiched between the first and second substrates. An alignment film is formed on one of the first and second substrates on the side facing the other substrate. A pre-tilt angle is imparted so that the ends of each liquid crystal molecule in the central region of the liquid crystal layer near the drive wiring line tilt away from the drive wiring line when a voltage is applied across each pixel electrode and the common electrode.
