A biometric sensing device and a display apparatus including the same are provided. The biometric sensing device includes a first thin film transistor, a second thin film transistor, and a photodiode. The first thin film transistor has a gate. The second thin film transistor has a semiconductor layer and a non-gate electrode terminal. The non-gate electrode terminal is electrically connected to the gate of the first thin film transistor. The photodiode contacts a semiconductor layer.
