Patent ID: 11892724
Assignee: HEFEI BOE DISPLAY TECHNOLOGY CO., LTD.
Field: Optics (Instruments)
Classification: CPC G | IPC G

Claim 9:
10. A method for manufacturing a display substrate, the display substrate being applied as a substrate on a light exiting side of a liquid crystal display panel, the method comprising:
forming a color filter layer on a base;
forming at least one cover layer on a side of the color filter layer away from the base, wherein the at least one cover layer comprises a first cover layer which is in contact with the color filter layer;
forming 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
forming a spacer which is positioned on the side of the first cover layer away from the base and is in contact with one of the at least one cover layer,
the method further comprises:
before forming the spacer, performing a plasma process on a surface of the first cover layer;
forming a first alignment layer in one-to-one correspondence with the optical compensation layer, each first alignment layer being formed before forming the optical compensation layer corresponding thereto;
wherein the forming each optical compensation layer comprises:
forming and curing a liquid crystal material layer to form the optical compensation layer.
