Claim:
1. A polarizer comprising: a polarizing film or polarizing element; and a protective film attached to a side or both sides of the polarizing film or polarizing element, wherein the protective film comprises: wherein the pressure sensitive adhesive layer comprises a cured product of a pressure-sensitive adhesive composition satisfying a condition of General Formula 1 given below: wherein ΔX represents an absolute value of a phase retardation (R wherein n wherein the base film is a saturated cycloolefin film; an olefin thermoplastic resin film having a substituted or unsubstituted imide group in its side chain; a thermoplastic resin film having a substituted or unsubstituted phenyl group and nitrile group in its side chain; or an acrylic film, wherein a stress optical coefficient of the saturated cycloolefin film; the olefin thermoplastic resin film having a substituted or unsubstituted imide group in its side chain; the thermoplastic resin film having a substituted or unsubstituted phenyl group and nitrile group in its side chain is 6 brewster or less, and the stress optical coefficient of the acrylic film is 3 brewster or less, and wherein the pressure sensitive adhesive composition comprises a compound having a positive stress optical coefficient expressed by Formula 3 or Formula 4: where B represents a single bond, —CH═N—, —N═N—, —N═N(O)—, —COO—, —CH Z is C—W or N; Q R l, m, n, and o are independently an integer of 0 to 2, and l+m+n+o is an integer greater than 2; E and F are independently hydrogen, halogen, cyano, —R G
