Abstract
A wavelength conversion element includes a substrate, a wavelength conversion layer, and a first inorganic interstitial layer. The wavelength conversion layer is disposed on the substrate. The wavelength conversion layer includes an inorganic adhesive and a wavelength conversion material, and the wavelength conversion material is mixed with the inorganic adhesive. The first inorganic interstitial layer is disposed between the wavelength conversion layer and the substrate. A projection device having the wavelength conversion element is further provided, and a manufacturing method of the wavelength conversion element is also provided. The wavelength conversion element manufactured by using the manufacturing method of the invention may improve conversion efficiency and thermal conductivity. The projection device of the invention may reduce the problem that the image brightness decreases.
