Abstract
A reflective filter including a substrate and an optical film structure disposed on the substrate is provided. The optical film structure includes a reflective layer, a spacing layer, a transflective layer and a transparent layer in sequence. Depending on the reflection and interference phenomenon form the layers of the optical film structure, a colored light within narrow band could be filtered by the reflective filter in order to enhance the color saturation of an image.
