摘要:
A display device includes a plurality of pixels, each of which has a drive transistor, an organic EL element and a writing capacitor, in which the drive transistor controls a luminous time period of the organic EL element by a writing signal voltage and a sweep signal so that the writing signal voltage is written into the writing capacitor independent from a characteristic variation caused by a deterioration due to the temperature and time lapse of using the organic EL element, thereby making a luminous time period long when the deterioration occurs with increase of an internal resistance of the organic EL element, and compensating a luminance degradation caused by the deterioration to solve a burn-in state of fixed pattern.
