The present invention relates to an electronic wall clock in which the brightness of the indicator is automatically adjusted according to the brightness of the clock. Since the light emitting display of the conventional electronic wall clock is fixed by setting the amount of light of the time display for easy identification based on the daytime, the brightness is too bright in the dark night, which causes eye fatigue and sleep disturbances, and also shortens the life of the light emitting display.
