Patent ID: 8519344

Claim:
A radiation imaging apparatus comprising: a substrate; a pixel region, on said substrate, including a plurality of pixels arranged in a matrix, each pixel having a conversion element and a switching element, said conversion element having a first electrode, a second electrode, and a semiconductor layer arranged between said first electrode and said second electrode, and said switching element being connected to said first electrode; a plurality of first lines each extending along a first direction of the matrix, wherein said plurality of first lines are arrayed along a second direction perpendicular to the first direction, each of said plurality of first lines is connected to said switching elements of pixels of said plurality of pixels, which are arranged along the first direction of the matrix, wherein a first voltage is applied to said plurality of first lines; a plurality of second lines each extending along the first direction, wherein said plurality of second lines are arrayed along the second direction, each of said plurality of second lines is connected to said second electrodes of said conversion element of pixels of said plurality of pixels, which are arranged along the first direction, and wherein a second voltage is applied to said plurality of second lines; a third line which is not arranged in said pixel region and is arranged outside said pixel region, wherein said third line extends along a direction parallel to the second direction of the matrix, and said third line is connected to said plurality of second lines; and a plurality of intersections at which said plurality of first lines and said third line intersect with each other without contacting each other, wherein each of said plurality of intersections is arranged outside said pixel region and includes: a semiconductor layer arranged between said first line and said third line; and a carrier-blocking portion arranged between said semiconductor layer of said intersection and said first line.
