Abstract
A color filter substrate and a manufacturing method thereof, and a display device are disclosed. The color filter substrate includes: a base substrate, a plurality of color filter units of different colors arranged on a side of the base substrate, and a 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 is capable of increasing a light transmission rate of at least one color filter unit. The effect of improving the light transmission rate can be realized.

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, and
- a 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 nλlight/4, where n is an odd number, and λlight 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.
A manufacturing method for a color filter substrate, comprising:
