Abstract:
1. An image detector, comprising: a plurality of scan lines disposed in parallel; a plurality of data lines provided so as to cross with the scan lines, the plurality of data lines being formed in a metal layer that is different from a metal layer in which the scan lines are formed, with an insulating film formed between the two metal layers; thin film transistors connected with the scan lines and data lines and provided in a matrix; sensor sections comprising a semiconductor film that generates charges when irradiated with electromagnetic radiation, the sensor sections being connected to the thin film transistors and provided in a matrix; and a plurality of common lines disposed so as to commonly apply bias voltage to the sensor sections provided in a matrix, the plurality of common lines being formed in a first metal layer that is below the semiconductor film of the sensor sections and is a different metal layer from a second metal layer in which the scan lines are formed, and is a different metal layer from a third metal layer in which the data lines are formed, and there being insulating film formed between adjacent first, second and third metal layers, wherein the first, second and third metal layers are formed at different levels in a vertical structure.
