A light emitting device has a plurality of pixels, each of which includes a drive transistor, a light emitting element and signal lines, a property parameter acquisition circuit which acquires property parameter, a signal correction circuit that generates a corrected gradation signal by correcting the image data based on the property parameter, and a drive signal impressing circuit that impresses a drive signal, generated based on the corrected gradation signal, on the pixel to drive it. The property parameter is constituted of a threshold voltage, a current amplification factor and its irregularity of the drive transistor, and is acquired based on measured voltages of the signal lines after each of a plurality of predetermined settling times elapses from the time when the light emitting device cuts off a voltage subsequent to impressing the voltage on each pixel for a predetermined length of time. |
