APR plate

The utility model discloses an APR (Asahikasei Photosensitive Resin) plate. The APR plate comprises a protective film, wherein an APR layer is formed on the protective film; a plurality of concave pits used for accumulating polyimide are formed on the surface of the APR layer; the depth and patterns of the concave pits are respectively matched with those of first parts of sub-pixels on a liquid crystal display substrate; and each sub-pixel comprises a raised first part and a second part except for the first part. by adopting the scheme provided by the utility model, the problem that a polyimide film at the higher part of the liquid crystal display substrate is too thin or even omitted is solved, and the thickness of the polyimide film at the higher part of the liquid crystal display substrate is increased, so that the liquid crystal orientation capability of corresponding parts is improved, and light leakage of the pixels is avoided.
