Abstract
A photo-detecting apparatus in which the time taken to read out a detection signal is decreased, and thus, a frame rate of the photo-detecting apparatus is improved. A photo-detecting pixel includes a photosensitive device for generating a first detection signal by photoelectrically converting incident light; a first transistor for generating a detection current by receiving the first detection signal generated by the photosensitive device via a gate terminal of the first transistor; a second transistor for forming a first current path with the first transistor, in response to a read signal input via a gate terminal of the second transistor; and a third transistor for delivering a voltage in accordance with the detection current to a data line, in response to a gate signal applied to a gate terminal of the third transistor.
