Beschreibung
Zusammenfassung:	A microfluidic detection device including a circuit substrate and a transparent substrate is provided. The circuit substrate is provided with at least one first light emitting device, a photodetector and a control circuit. The at least one first light emitting device is used to emit a detection beam. The photodetector is used to receive the detection beam and send out a sensing signal. The control circuit is electrically connected to the at least one first light emitting device and the photodetector. The transparent substrate overlaps the circuit substrate, and is provided with a microfluidic channel and a light guide structure. The light guide structure has a light incident surface and a light exiting surface. The light guide structure extends from the light incident surface and the light exiting surface to the microfluidic channel respectively, and is adapted to transmit the detection beam into and out of the microfluidic channel. The light incident surface of the light guide structure is disposed correspon
