Patent ID: 7973747

Claim:
A display device comprising: a display unit comprising: a plurality of scan electrodes extending along a first direction and arranged parallel to each other; a plurality of data electrodes extending along a second direction crossing the scan electrodes and arranged parallel to each other; and a plurality of pixels, each pixel at which a pair of the scan electrode and the data electrode cross each other, wherein each pixel has a light emitting layer and a dielectric layer interposed between the scan electrode and the data electrode; a writing pulse supplying unit configured to select pixels for emitting light, and supply a writing voltage pulse train so as to apply a voltage not less than emission starting voltage to light emitting layers of the selected pixels; maintaining pulse supplying unit configured to supply maintaining voltage pulse train; and an erasing pulse supplying unit configured to supply an attenuation voltage pulse train, to the light emitting layer of each pixel, wherein: the attenuation voltage pulse train starts at a voltage not more than emission starting voltage at which the light emitting layer starts light emission, and starts from a voltage of reverse polarity with respect to a polarity of a last voltage pulse of the maintaining voltage pulse train, polarity of the attenuation voltage pulse train is alternately reversed between positive and negative, and absolute voltage values of the attenuation voltage pulse train decreases gradually so that a subsequent pulse has a smaller absolute voltage value than a previous pulse, and the light emitting layer performs self-electroluminescence emission when a voltage not less than the emission starting voltage is applied to the light emitting layer.
