A display panel, a display device, and a driving circuit including both a touch sensor configuration and a photosensor configuration are disclosed. The driving circuit comprises a multi-sensing circuit electrically connected to a plurality of common electrodes, disposed in a display panel, through a plurality of read-out lines disposed in the display panel; and a photo-driving circuit driving a plurality of photo-driving lines and a plurality of photo-control lines through which a photo-driving signal and a photo-control signal are transferred to a plurality of phototransistors disposed in the display panel, wherein each of the plurality of phototransistors comprises a gate electrode to which the photo-control signal is applied, a first electrode to which the photo-driving signal is applied, and a second electrode serving as a signal output node, with a signal being output to the second electrode in response to illumination light, and the multi-sensing circuit receives the signal, output from the second electrode of each of the plurality of phototransistors, through a corresponding read-out line among the plurality of read-out lines. A high aperture ratio is obtained since electrode and line structures for touch sensing and photosensing are efficiently designed.
