Patent ID: 8476596

Claim:
A thin film transistor (TFT) array substrate for an X-ray detector, comprising: a substrate including a plurality of pixel areas each including a transistor area in which a TFT is formed, and a photodiode formed in a photodiode area; a first wire extending through the plurality of pixel areas on the substrate, wherein the first wire is formed in a first layer disposed in a lower portion of a photodiode layer in which the photodiode is formed, in at least one portion of the transistor area, and wherein the first wire is formed in a second layer disposed in an upper portion of the photodiode layer in the photodiode area; a second wire, insulated from the first wire, and extending in the plurality of pixel areas and formed in the second layer; and at least one TFT formed in the transistor area and electrically connected to at least one of the first wire and the second wire.
