摘要：
Gradation is improved in image formation by image-forming apparatus employing a light emitting elements such as organic light-emitting element, and image quality. A light-emitting element is provided in which the emission and no emission of light is controlled by the intensity of the input signal from the scanning line and the signal line by flowing constant electric current to a two-input-differential connection circuit one of which is connected to the light-emitting element.
