X-ray detector

An X-ray detector comprising:

• a substrate divided into a light detection area and a non-detection area and comprising a plurality of pixels;
• a photosensitive element on the light detection area;
• a circuit unit on the non-detection area and electrically connected to a lower portion of the photosensitive element;
• a plurality of wires on the non-detection area and electrically connected to the circuit unit;
• a device passivation layer covering at least the circuit unit and the plurality of wires;
• an insulating layer covering the device passivation layer;
• a light wavelength conversion layer on the insulating layer over an entire surface of the substrate;
• and
• a shielding part disposed between the insulating layer and the light wavelength conversion layer to shield the non-detection area.

An X-ray detector comprising:

• a substrate divided into a light detection area and a non-detection area and comprising a plurality of pixels;
• a photodiode on the light detection area;
• a thin film transistor on the non-detection area and electrically connected to a lower portion of the photodiode;
• a plurality of wires electrically connected to the thin film transistor and positioned on the non-detection area;
• at least one insulating layer disposed so as to cover at least the thin film transistor and the plurality of wires;
• a device passivation layer that covers at least the thin film transistor and the photodiode and is disposed below the insulating layer;
• a scintillator layer disposed on the at least one insulating layer over an entire surface of the substrate;
• and
• a shielding part disposed between the device passivation layer and the at least one insulating layer to shield the non-detection area.
