Abstract

An electronic device with an auxiliary light includes a display module. The display module comprises a substrate, a display area and a light-emitting area. In this case, the substrate has a first surface and a second surface which is opposite to the first surface. The display area has a first electrode, an organic functional layer and a second electrode. The organic functional layer is sandwiched between the first electrode and the second electrode. The first electrode is disposed on the first surface of the substrate. The light-emitting area has a third electrode, an organic functional layer and a fourth electrode. The organic functional layer is sandwiched between the third electrode and the fourth electrode, the third electrode is disposed on the first surface or the second surface of the substrate.
