    • The present invention discloses a color filter includes a substrate layer and a medium grating layer, wherein the medium grating layer, arranged on the substrate layer, has a grating structure of periodic arrangement. The color filter is characterized in that: the medium grating layer is provided with a metal profiling film, which covers the ridge portion of the grating structure, one or two sides of the lateral portion of the grating structure, and a part of the groove portion of the grating structure, with the area of the groove portion of the grating structure covered by the metal profiling film occupying 30%-95% of the total area of the lateral portion and the groove portion. By providing the metal profiling film, this invention can break the condition of the original metal surface plasmon resonance, and reduce influence of the incident angle of light on the resonance condition, thus achieving the filtering effect within a relatively wide range of angle.
    • 本发明公开了一种滤色器,其包括基底层和介质光栅层,其中布置在基底层上的介质光栅层具有周期排列的光栅结构。 滤色器的特征在于:介质光栅层设置有金属成型膜,其覆盖光栅结构的脊部,光栅结构的侧部的一侧或两侧,以及槽部的一部分 光栅结构的槽部的面积被金属成型膜覆盖的面积占侧面部分和槽部的总面积的30%〜95%。 通过设置金属型膜,本发明可以破坏原始金属表面等离子体共振的状态,并且减小光入射角对谐振条件的影响,从而在相对较宽的角度范围内实现滤波效果。
