Abstract
A reflection film including a reflection film substrate and a wavelength conversion layer is provided. The wavelength conversion layer is disposed on the reflection film substrate. The wavelength conversion layer includes a wavelength conversion material, a plurality of nanoparticles and a base material. Since the reflection film of the invention includes the wavelength conversion material and the plurality of nanoparticles, the backlight brightness and the color saturation of the display using the reflection film of the invention are improved.
