PROBLEM TO BE SOLVED: To provide an active thin film EL matrix that is driven at a high speed, and to provide its driving method. SOLUTION: By synchronizing the power supply which drives EL elements and control signals that control light emitting/light non-emitting of the elements, all of the writing of light emitting data, light emitting driving and stopping of light emitting driving operations are conducted in one scanning interval for EL element light emitting. Thus, the active thin film EL matrix is driven at a speed much higher than a conventional speed and luminance of the entire matrix can be made uniform.
