RADIATION IMAGING PANEL, RADIATION IMAGING DEVICE, AND RADIATION IMAGING SYSTEM

WIPO Patent Application WO/2019/097847

A1

The present invention comprises: a substrate; a first photoelectric conversion unit that includes a plurality of first photoelectric conversion elements disposed on a first surface of the substrate; a first wavelength conversion unit that includes a scintillator layer disposed so as to cover the first photoelectric conversion unit; and a second wavelength conversion unit disposed so as to cover a second surface of the substrate on the side opposite the first surface. The second wavelength conversion unit includes partition walls that define a plurality of segments having prescribed shapes, and a plurality of scintillator parts respectively disposed in the plurality of segmented regions. The partition walls inhibit light generated at the plurality of scintillator parts from diffusing between the plurality of scintillator parts. In an orthographic projection of the first surface, the partition walls are disposed so as to overlap, along the row direction and/or the column direction where the plurality of first photoelectric conversion elements are disposed, regions between the photoelectric conversion elements that are adjacent to each other from among the plurality of first photoelectric conversion elements.
