1. A color filter substrate, comprising a base substrate, a black matrix and a color filter layer which are located on the base substrate, a quantum dot layer which is located on a side of the color filter layer away from the base substrate, and a barrier layer which is located on a side of the black matrix away from the base substrate, wherein the black matrix defines a position of the color filter layer, the barrier layer defines a position of the quantum dot layer, the color filter substrate further comprises a first inorganic layer, and the first inorganic layer at least comprises:
a first portion located between the color filter layer and the quantum dot layer;
a second portion located between the quantum dot layer and the barrier layer; and
a third portion on a side of the barrier layer away from the base substrate the color filter substrate further comprises:
a second inorganic layer, wherein the second inorganic layer comprises:
a fourth portion located on a side of the color filter layer proximal to the base substrate;
a fifth portion located between the color filter layer and the black matrix; and
a sixth portion located between the black matrix and the barrier layer, the color filter substrate further comprises:
a plurality of pillar supports, wherein the plurality of pillar supports are spaced apart on a side of the barrier layer away from the base substrate.
