Abstract:
A semiconductor apparatus comprising a plurality of pixels arrayed in a matrix, each pixel comprising a capacitor or a photoelectric conversion element, and a thin film transistor connected to the capacitor or the photoelectric conversion element, said capacitor or photoelectric conversion element being comprised of a first electrode and a second electrode, said thin film transistor being comprised of a first main electrode and a second main electrode, and a control electrode for controlling electric conduction between these two main electrodes, the first electrode of said capacitor or photoelectric conversion element being connected to the first main electrode of said thin film transistor in each of said pixels, in which a control electrode line extending in a first direction of said matrix pixel array connects the control electrodes of the thin film transistors of the respective pixels in every pixel line in the first direction, in which a bias line extending in a second direction of said matrix pixel array connects the second electrodes of the capacitors or photoelectric conversion elements of the respective pixels in every pixel line in the second direction, and in which a signal transfer line extending in the second direction of said matrix pixel array connects the second main electrodes of the thin film transistors of the respective pixels in every pixel line in the second direction,wherein an end of said bias line on an opposite side to a connection side to a common electrode driver for application of a bias is electrically connected by a redundant wire to an end of another bias line on the opposite side to the connection side to the common electrode driver for application of the bias.
