Abstract
A first pixel circuit and a third pixel circuit are connected to a first scan signal line, and a second pixel circuit and a fourth pixel circuit are connected to a second scan signal line. Of two first pixel circuits connected to a common, first scan signal line, a capacitive element in the first pixel circuit in a group that is located farther in a row direction from a center of a display area has a larger capacitance value than does a capacitive element in the first pixel circuit in a group that is located closer.
