1. A color filter substrate, comprising a base substrate and a color filter formed on the base substrate, wherein the color filter includes a plurality of color areas;

  • the color filter substrate further comprises a plurality of antireflective films,wherein each antireflective film in the plurality of antireflective films corresponds to one color area in the color filter,the antireflective film is configured to reduce a reflectively of the light of which the color is the same with the color of the corresponding color area,refractive indexes of the plurality of antireflective films in different color areas are different, thickness of the plurality of antireflective films in different color areas are different,the color filter substrate further comprises a protective layer;

    the protective layer is disposed on an Incident side of the color filter substrate;

    the plurality of antireflective films are disposed between the productive layer and the plurality of color areas; and

    a reflective Index of each of the plurality of antireflective films is between a refractive index of the corresponding color area and a refractive index of the protective layer,the plurality of color areas comprises a red area, a green area, and a blue area, refractive of the red area is n1;

    refractive index of the green area is n2;

    refractive index of the blue area is n3; and

    refractive index of the protective layer 2 is n0;

    refractive index N1 of the antireflective film between the red area and the protective layer is between n0 and n2;

    refractive Index N2 of the antireflective film between the green area and the protective layer is between n0 and n2; and

    refractive index N3 of the antireflective film between the blue area and the protective layer is between n0 and n3.
