Abstract:
In a driving circuit of a spontaneous light emitting display device driven as an active matrix, a noise current is prevented from flowing in a light emitting element when compensating for a threshold voltage of a transistor for controlling current flowing to the emitting element, enhancing precision in luminance. A switching element for short-circuiting electrodes of the spontaneous light emitting element for a period in which the noise current flows in the light emitting element bypasses the noise current.
