Abstract

A polarizer according to the patent invention which is used for a polarizing film having an adhesive layer on one side of the polarizer is configured to contain boric acid and a polyvinyl alcohol-based resin, to have a thickness of 10 µm or less, and to have an optical property satisfying the condition represented by the expression: P > -(10 0.929T - 42.4 - 1) × 100 (when T < 42.3) or P ≥ 99.9 (when T ≥ 42.3), wherein T represents the single-body transmittance and P represents the polarization degree. In addition, a boric acid content (a) measured from one side of the polarizer, the one side to be provided with the pressure-sensitive adhesive layer, is less than a boric acid content (b) measured from the other side. The polarizer according to the patent invention can reduce defects due to through cracks and nano-slits even when the polarizer has predetermined optical properties and a thickness of 10 µm or less.
