<p>An X-ray imaging device 1 includes an X-ray detection section 2, a cold electron source 3, and a light-shielding coating layer 9. The X-ray detection section 2 includes an X-ray conversion layer 13 made of an X-ray converter material which generates electric charges upon incidence of an X-ray, a first charge injection blocking layer 14 formed on an incidence surface 13a of the X-ray conversion layer 13, and a second charge injection blocking layer 15 formed on a rear surface 13b of the X-ray conversion layer 13. The cold electron source 3 has a plurality of electron emission sections arranged in a matrix form, each of the electronic emission sections being capable of emitting electrons toward the second charge injection blocking layer 15 of the X-ray detection section 2. The light-shielding coating layer 9 blocks incidence of the visible light into the X-ray detection section 2.</p> |
