Claim 0:
1. A display substrate, applied as a substrate on a light exiting side of a liquid crystal display panel, the display substrate comprising:
a base;
a color filter layer disposed on the base;
at least one cover layer positioned on a side of the color filter layer away from the base, and comprising a first cover layer which is in contact with the color filter layer;
at least one optical compensation layer, wherein each optical compensation layer is positioned on a side of the first cover layer away from the base and is configured to compensate a phase delay of light emitted from a liquid crystal layer of the liquid crystal display panel; and
a spacer positioned on the side of the first cover layer away from the base and being in contact with one of the at least one cover layer,
wherein the optical compensation layer is a cured liquid crystal film, the display substrate further comprises:
a first alignment layer in one-to-one correspondence with the optical compensation layer, the first alignment layer being located between the optical compensation layer corresponding thereto and the first cover layer; and
a second alignment layer;
wherein each optical compensation layer is located between the second alignment layer and the first alignment layer.
