[0045] In some exemplary embodiments, the polarizer of the embodiments of the present application further includes: a first TAC film 103.

[0046] In some exemplary embodiments, the TAC (Triacetate cellulose) film, i.e., the triacetate fiber film, is a film obtained by processing powdery TAC particles through processes such as dissolution, filtration, plasticization, injection molding, and drying, and has excellent light uniformity, transparency, acid and alkali resistance, and ultraviolet resistance.
