1. the manufacture method of a PSVA liquid crystal panel, it is characterised in that comprise the steps:

  • Step 1, offer upper substrate (10) and infrabasal plate (20), be respectively coated one layer of alignment film material on the side of described upper substrate (10) and infrabasal plate (20), forms alignment film (30);

    Described alignment film material comprises polyimide-based polymer, and the molecule of this polyimide-based polymer includes the polymerisable response type group (32) of polyimides main chain (31) and side chain;

    Step 2, it is provided with on the side of alignment film (30) injects includes the liquid-crystal composition of liquid crystal molecule (41) at upper substrate (10) or infrabasal plate (20), then upper substrate (10) and infrabasal plate (20) is made to be provided with the side of alignment film (30) facing, by upper substrate (10) and infrabasal plate (20) to composition box, form the liquid crystal layer (40) between upper substrate (10) and infrabasal plate (20), obtain liquid crystal cell;

    Step 3, upper substrate (10) and infrabasal plate (20) are applied certain voltage, and liquid crystal cell is carried out irradiation under ultraviolet ray, there is polyreaction in the response type group (32) on the interior polyimide polymer lateral chain of alignment film (30) on upper substrate (10) and infrabasal plate (20) opposite side, make the liquid crystal molecule (41) in liquid crystal layer (40) form tilt angle under irradiation under ultraviolet ray.
