Abstract: Provided is a photo detecting apparatus. The photo detecting apparatus includes a thin film transistor array on a first surface of a substrate having a specific light transmissivity and a photo diode structure between the first surface and the thin film transistor array. The photo diode structure is implemented to receive and process an electromagnetic radiation through a second surface of the substrate.
