Abstract
A TFT type optical detecting sensor includes a capacitor, a sensor TFT, and a switching TFT each having an active layer with a channel having an elongated width. The width of the channel of the sensor TFT is substantially defined by a distance of a side of the pixel excluding the switching source wire and sensor drain wire. The first electrode of the capacitor of the optical detecting sensor is electrically connected to the sensor gate electrode of the sensor TFT.
