1. A color filter substrate, comprising:

  • a base substrate,a plurality of color filter units of different colors arranged on a side of the base substrate, anda light anti-reflection layer arranged on the base substrate and on a light emergent side of the color filter units, the light anti-reflection layer being capable of increasing a light transmission rate of at least one color filter unit,wherein a position where the light anti-reflection layer is arranged on the base substrate corresponds to a position where at least one color filter unit is arranged on the base substrate, a thickness of the light anti-reflection layer is relevant to a wavelength of color light corresponding to at least one color filter unit, and the light anti-reflection layer includes a plurality of light anti-reflection units in one-to-one correspondence with the color filter units,a thickness of each light anti-reflection unit is nλ

    light/4, where n is an odd number, and λ

    light is a wavelength of the color light corresponding to the color filter unit corresponding to the light anti-reflection unit,the color filter substrate is an array substrate with a color filter integrated thereon; and

    the light anti-reflection layer is arranged on a side of the color filter away from the base substrate.
