Abstract:
A display device having a pixel section pixel circuits, scan lines, capacity lines, a drive circuit driving the scan lines and the capacity lines selectively, a generation circuit generating a common voltage signal switching in level at a predetermined cycle, and a correction circuit correcting the signals driving the capacity lines of the drive circuit, wherein each pixel circuit contains a display element and holding capacitor, a first pixel electrode of the display element pixel cell, a first electrode of the holding capacitor, and one terminal of the switching element are connected, a second electrode of the holding capacitor is connected to the capacity lines arrayed in a corresponding row, and the common voltage signal is applied in a second pixel electrode of the display element. The correction circuit has a monitor circuit monitoring the pixel potential of the pixel section and correcting a signal driving the capacity lines taking into consideration the optical characteristics of the display element based on the monitor result of the monitor circuit.
