Claim Text:
1. A display panel, comprising: a first substrate; a second substrate, arranged parallel to the first substrate; an anode/cathode, formed on the first substrate; a cathode/anode, formed on the second substrate; a first alignment layer, provided on the anode/cathode and comprising a plurality of first sub-alignment layers having a first alignment direction and a plurality of second sub-alignment layers having a second alignment direction alternately arranged in a first direction, and a angle between the first alignment direction and the second alignment direction being 90 degrees; a second alignment layer, provided on the cathode/anode and comprising a plurality of third sub-alignment layers having the first alignment direction and a plurality of fourth sub-alignment layers having the second alignment direction alternately arranged in the first direction, and the first sub-alignment layers corresponding to the third sub-alignment layers in a position, and the second sub-alignment layers corresponding to the fourth sub-alignment layers in a position; and a light emitting layer, provided between the first alignment layer and the second alignment layer, which comprises a liquid crystal polymer doped with organic light emitting material and is configured to emit a polarized light wherein a plurality of sub-pixel units comprises a plurality of red sub-pixel units, a plurality of green sub-pixel units and a plurality of blue sub-pixel units, wherein the light emitting layer corresponding to the red sub-pixel units comprises a fluorene/D-A type naphthothiadiazole/benzoselenadiazole copolymer or a fluorene/thiophene/benzoselenadiazole copolymer, the light emitting layer corresponding to the green sub-pixel units comprises poly(9,9-dioctylfluorene-alt-benzothiadiazole)(PFBT) or vinyl fluorene-vinyl phenothiazine copolymer, and the light emitting layer corresponding to the blue sub-pixel units comprises poly(9,9-dihexylfluorene)(PF2/6) or dioctylfluorene(PFO), the first alignment layer and the second alignment layer are a doping polyimide alignment layers, the doping polyimide alignment layer is a polyimide alignment layer doped with star-amine or a polyphenylene vinylene prepolymer alignment layer.
