The image pickup apparatus of the radiological imaging apparatus of the present invention includes many detector units, a ring-shaped detector support member and an X-ray source circumferential transport apparatus. The apparatus comprises an illumination unit and at least one detection unit. The display device also includes a thin film transistor driving the electroluminescent element, and a protection film disposed over the second electrode and being configured to prevent a penetration of moisture into the electroluminescent element. The transmission gate transmits the clock signal when at an ON condition and does not transmit the clock signal when in an OFF condition.
