Abstract
A wavelength conversion element includes a substrate, a reflective layer, an inorganic light luminescence layer and an organic light luminescence layer. The reflective layer is disposed over the substrate. The inorganic light luminescence layer is disposed over the reflective layer and includes a first fluorescent material. The organic light luminescence layer is disposed between the reflective layer and the inorganic light luminescence layer, and includes a second fluorescent material. A refractive index of the inorganic light luminescence layer is greater than that of the organic light luminescence layer, and a thickness of the inorganic light luminescence layer is greater than a thickness of the organic light luminescence layer.
