Patent ID: 7812313

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, and 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 of the pixels including respective ones of the switching elements and of the conversion elements; a plurality of signal wirings including the second metal layer, and being connected to the plurality of switching elements of the column direction; a plurality of bias wirings including the fourth metal layer, and being connected to the plurality of conversion elements; and an external signal wiring portion including the first metal layer outside the pixel region, and being connected to the signal wirings, wherein the external signal wiring portion and the bias wiring intersect each other.
