Reflective color filters with metal-dielectric thin films in visible range are designed based on induced reflection method. High-absorption chromium and high-reflection aluminum enable these color filters to acquire both high reflectance and cut-off level in a broadband spectral region. Red, green and blue reflective filters with the reflectance larger than 72% and wide color gamut are obtained by adjusting thickness of their matching dielectric layers respectively for proper admittance matching. Filter samples are experimentally fabricated and the measured results agree well with those of the simulation. According to the halftone technique, filter arrays with different area duty ratios are prepared by lithography and stripping technology to realize optical reflective units with high resolution and intermediate colors among red, green and blue.
