Abstract
A multilayer light-filtering structure includes a substrate, a light-filtering layer and a patterned light-blocking layer. The light-filtering layer is disposed on a surface of the substrate, in which the light-filtering layer has a first surface away from the substrate, and the light-filtering layer includes a plurality of high refractive index films and a plurality of low refractive index films. The low refractive index films are correspondingly overlapped with the high refractive index films. The patterned light-blocking layer is disposed on the first surface and includes a plurality of metal material films and a plurality of dielectric films. The dielectric films are correspondingly overlapped with the metal material films.
