Abstract

The invention discloses a polarizer with a TAC layer arranged on one side, and the polarizer comprises a protective layer, a first PSA layer, a PVA layer and the TAC layer, which are disposed in a stepwise fitting manner. The invention also discloses a preparation method of the above polarizer. The polarizer with the TAC layer arranged on one side provided by the invention can meet the performance requirements of the polarizer to make the polarizer thinner and lighter, and can save the production cost and improve the competitiveness of the enterprise. The preparation method of the polarizer with the TAC layer arranged on one side provided by the invention is simple, and can effectively solve the problem of warpage and shrinkage of the polarizer provided with the TAC layer on one side, and also solve the problem that the glass substrate is bent after the polarizer is attached to the glass substrate.

Description

technical field [0001] The invention relates to the technical field of polarizers, in particular to a polarizer with a TAC layer on one side and a preparation method thereof. Background technique [0002] The polarizer is an optical functional film that produces polarized light. The imaging of the liquid crystal panel must rely on polarized light, so the polarizer is a key part of the liquid crystal panel. The basic structure of the polarizer is composed of the following film materials in sequence: protective film, cellulose triacetate (TAC), polyvinyl alcohol (PVA), cellulose triacetate (TAC), pressure-sensitive adhesive (PSA), release type The polarizing film is PVA, and the TAC film has high light transmittance and certain mechanical strength. It is compounded on both sides of PVA. Although it can protect PVA, the two layers of TAC layer make the thickness of the polarizer It is too thick to meet the needs of thinner and multifunctional polarizers. [0003] In the LCD m...
