Patent ID: 7629564

Claim:
A conversion apparatus, comprising: an insulating substrate; a pixel region including a switching element region in which a plurality of switching elements each including a first metal layer disposed over the insulating substrate, an insulating layer disposed over the metal layer, a first semiconductor layer, and a second metal layer are arranged in row and column directions, a conversion element region in which a plurality of conversion elements each including a lower electrode made of a third metal layer disposed over the switching element region, a second semiconductor layer disposed over the lower electrode, and an upper electrode made of a fourth metal layer disposed over the second semiconductor layer are arranged in row and column directions, and each pixels including the switching elements and the conversion elements; a plurality of signal wirings including the second metal layer, signal wirings being connected to the plurality of switching elements of the column direction; a plurality of bias wirings including the fourth metal layer, bias wirings being connected to the plurality of conversion elements; an external signal wiring portion including the fourth metal layer outside the pixel region, the external signal wiring portion being connected to the signal wirings; and an external bias wiring portion including the first metal layer outside the pixel region, the external bias wiring portion being connected to the plurality of bias wirings, wherein the external signal wiring and the external bias wiring intersect each other.
