Abstract
A wavelength conversion element includes a substrate, a wavelength conversion layer and an anti-reflective layer. The wavelength conversion layer is disposed on the substrate. The anti-reflective layer is disposed on the wavelength conversion layer. The anti-reflective layer includes a first adhesive layer having a plurality of pores. A thickness of the anti-reflective layer is 500 nm to 3000 nm, a pore diameter of each of the plurality of pores is 100 nm to 2500 nm, and the thickness of the anti-reflective layer is greater than the pore diameter of the plurality of pores. A manufacturing method of the aforementioned wavelength conversion element is also provided, through which the wavelength conversion element has the anti-reflective effect.
