<p>A color filter (200) includes a substrate layer (210) and a medium grating layer (220) provided on the substrate layer. The medium grating layer has a metal profiling film (230) and a grating structure which is periodically arranged. The metal profiling film covers the ridge part (221) of the grating structure, covers the side part (223) of one side or two sides of the grating structure, and covers a part of the groove part (222) of the grating structure. The area of the groove part of the grating structure covered by the metal profiling film is 30%~95% of the total area of the side part and the groove part. By providing the metal profiling film, the original plasma resonance condition of the metal surface is destroyed, and the effect on the resonance condition generated by the incident angle of the light is reduced, thereby the angle range of the filter can be widened.</p> |
