Polarizing plate for light-emitting display device, and light-emitting display device including same

A polarizing plate for light emitting display devices, comprising:

• a polarizing film;
• and
• a liquid crystal retardation film formed on one surface of the polarizing film, the liquid crystal retardation film comprising a laminate of a second retardation film and a first retardation film, the second retardation film comprising a discotic liquid crystal layer having an in-plane retardation Re of about 220 nm to about 280 nm and a degree of biaxiality NZ of about 0 to about 0.3 at a wavelength of 550 nm, the first retardation film comprising a nematic liquid crystal layer having an in-plane retardation Re of about 100 nm to about 150 nm and a degree of biaxiality NZ of about 0.3 to about 0.7 at a wavelength of 550 nm,
• wherein the nematic liquid crystal layer comprises photoreactive liquid crystals having a photosensitive functional group,
• wherein the nematic liquid crystal layer comprises a unit represented by Formula 1 or Formula 2:
• where p is an integer from 1 to 12;
• q is an integer from 0 to 12;
• X is a single bond, a C1 to C10 alkylene group, —O—, —S—, —SO—, —SO2—, —CH═CH—, —C≡C—, —N═N—, —COO—, —OCO—, or a C6 to C10 arylene group;
• R1 and R2 are each independently a hydrogen atom, a C1 to C10 alkyl group, a C1 to C10 alkoxy group, a C2 to C10 alkenyl group, a C2 to C10 alkynyl group, or a halogen atom;
• and W is a cinnamoyl group, a cinnamylidene group, a (meth)acryloyl group, a (meth)acryloyl group-containing group, a coumarin group, or a benzophenone group,
• where r is an integer from 0 to 12;
• s is 0 or 1;
• m is 0 or 1;
• n is an integer from 1 to 3;
