To provide a passive self-luminous device having a function for correcting a degradation of a light emitting element, which is capable of performing display with uniformity across a screen without occurrence of brightness variance. A counter counts an accumulated illumination time or an accumulated illumination time and illumination intensity in each pixel using a first image signal to store the count result in a volatile memory or a non-volatile memory. In a correction circuit, from the accumulated illumination time or the accumulated illumination time and illumination intensity, the first image signal is corrected according to a degree of degradation of each light emitting element based on correction data stored in advance in a correction data storage unit, to obtain a second image signal. With the second image signal, it is possible to eliminate the brightness variance and obtain a display with a uniformity across the screen in a display device, even when a light emitting element in a portion of pixels is degraded.
