Polarizing plate and liquid crystal display comprising the same

A polarizing plate comprising:

• a polarizer;
• a pattern layer arranged at a first side of the polarizer, the pattern layer comprising a first refractive index layer having at least one engraved pattern and a second refractive index layer having a filling pattern filling at least a portion of the engraved pattern, the engraved pattern having an aspect ratio of 1.0 or less, the first refractive index layer having a higher refractive index than the second refractive index layer, the first refractive index layer having a refractive index of 1.50 to about 1.65;
• and
• a first protective layer,
• the polarizing plate having a stack structure in which the polarizer, the second refractive index layer, the first refractive index layer and the first protective layer are sequentially stacked in that order, and the first refractive index layer is directly on the first protective layer,
• wherein the first protective layer comprises a base film comprising at least one resin of triacetylcellulose, polyethylene terephthalate, cyclic olefin polymer, and acrylic resins, and
• wherein the first protective layer comprises the base film and a primer layer on at least one surface of the base film, the primer layer has a refractive index of about 1.0 to about 1.6, and a ratio of the refractive index of the primer layer to a refractive index of the base film is about 1.0 or less.
