摘要：
Provided is a wavelength conversion plate having excellent luminous efficiency of a wavelength-converted light. The wavelength conversion plate includes a dielectric layer with nano pattern, a metal layer formed inside the nano pattern, and a wavelength conversion layer formed on the metal layer and having quantum dot or phosphor which wavelength-converts an excitation light to generate a wavelength-converted light.
