Patent ID: 8115177

Claim:
A radiation detection apparatus comprising: a sensor panel including a photoelectric conversion unit provided with a plurality of photoelectric conversion elements; a wavelength converter, disposed over the photoelectric conversion unit, for converting radiation into light detectable by the photoelectric conversion elements; a protective layer covering the wavelength converter, and having a base member and a metal layer disposed between the wavelength converter and the base member; an electroluminescence light source, having a light-emitting layer disposed between electrodes for applying an alternating current voltage across the light-emitting layer, for emitting light to the photoelectric conversion unit, wherein the electroluminescence light source is disposed between the wavelength converter and the base member, one of the electrodes is a light-transmitting electrode disposed between the wavelength converter and the light-emitting layer, and the other of the electrodes is the metal layer and functions to reflect the light converted by the wavelength converter to the photoelectric conversion elements and to emit light from the light-emitting layer to the photoelectric conversion elements; and an adhesive layer disposed between the light-transmitting electrode and the wavelength converter and disposed between the protective layer and the sensor panel, wherein the electroluminescence light source is bonded and fixed to the wavelength converter by the adhesive layer, and the protective layer is bonded and fixed to the sensor panel at the periphery of the protective layer.
