3 THIRD ORDER RESONANCE-BASED HIGH COLOR PURITY STRUCTURAL COLOR FILTER

摘要

Disclosed is a structural-color color filter. The structural-color color filter includes: a first reflective layer; a second reflective layer facing the first reflective layer; a first resonance layer disposed between the first reflective layer and the second reflective layer; a second resonance layer disposed between the first resonance layer and the second reflective layer; and an absorption layer disposed between the first resonance layer and the second resonance layer. Therefore, the structural-color color filter can emit light of high purity color.
