1. A display device comprising:

  • a pixel section having a plurality of pixel circuits, each writing video pixel data propagated through a switching element over a signal line, arranged in a matrix, a plurality of scan lines arranged so as to correspond to an array of rows of the pixel circuits and control conduction of the switching elements, a plurality of capacity lines arranged so as to correspond to an array of rows of the pixel circuits, a drive circuit for selectively driving the plurality of scan lines and the plurality of capacity lines, a generation circuit for generating a common voltage signal switched in level at a predetermined cycle, and a correction circuit for correcting the signals driving the capacity lines of the drive circuit, wherein each pixel circuit arrayed at the pixel section includes a display element having a first pixel electrode and second pixel electrode and a holding capacitor having a first electrode and second electrode, a first pixel electrode of the display element pixel cell and a first electrode of the holding capacitor are connected to one terminal of the switching element, a second electrode of the storage capacitor is connected to the capacity line arrayed at a corresponding row, a second pixel electrode of the display element is supplied with the common voltage signal, and the correction circuit has a monitor circuit for monitoring the pixel potential of the pixel section and corrects the signals driving the capacity lines considering the optical characteristics of the display elements based on the results of monitoring of the monitor circuit.
