Patent ID: 8629864

Claim:
A display device in which a plurality of pixels are arranged in a matrix form, corresponding to intersections of a plurality of data lines and a plurality of scan lines, wherein each pixel comprises: a light emitting element having a first electrode connected to a first power supply and which emits light according to a current that flows; a driving transistor having a source electrode connected to a second power supply and which supplies a drain current to a second electrode of the light emitting element; a data storage capacitor having a first electrode connected to a gate electrode of the driving transistor; and a first switch which is switched ON during a pixel selection period so that data of a data line is written to the data storage capacitor, and a second switch for controlling a connection between the second power supply and a second electrode of the data storage capacitor, wherein a potential of the second electrode of the data storage capacitor is changed between at least a partial period in the pixel selection period and at least a partial period in a pixel non-selection period, wherein the second electrode of the data storage capacitor and a reference power supply that is different from the second power supply are connected via a resistance, and wherein if a resistance between the data storage capacitor and the reference power supply is made R LR , an on resistance of the second switch is made Ron, and a number of pixels, in whichever of the horizontal or vertical direction of the display device has fewer pixels, is made M, Ron<R LR ×M/40 is satisfied.
