Example embodiments generally relate to a detector for electromagnetic radiation such as a detector comprising a first, pixelated electrode layer comprising a plurality of electrode pixels, a first layer comprising a plurality of tiles comprising a material configured to absorb and convert the electromagnetic radiation, and a second electrode layer, as well as a method of producing a detector for electromagnetic radiation, comprising providing a first, pixelated electrode layer comprising a plurality of electrode pixels, applying a plurality of tiles comprising a material configured to absorb and convert the electromagnetic radiation on the first, pixelated electrode layer, and applying a second electrode layer on the first layer.

An imaging element disposed on a substrate includes a photodetector, a thin-film transistor disposed between the photodetector and the substrate, and a signal line configured to transmit a signal from the photodetector via the thin-film transistor. At least a part of the signal line includes a first signal line layer and a second signal line layer directly laid one above the other. At least a part of the thin-film transistor is covered with the photodetector in a planar view. The second signal line layer extends outside the photodetector in a planar view. The first signal line layer is included in the same metal layer pattern as a drain electrode of the thin-film transistor and is continued to the drain electrode.

Proposed is an X-ray detector. The X-ray detector includes a detector module including a sensor assembly in which a photoconductive layer formed of perovskite is formed, a case providing a space in which the detector module is positioned and including at least one metal layer, and a desiccant filling an internal space of the case in a state in which the detector module is accommodated in the case.
