Abstract
A polarizing plate and an optical display comprising the same. The polarizing plate includes a polarizer; and a bonding layer and a first polarizer protective film sequentially stacked on a lower surface of the polarizer, wherein the first polarizer protective film includes a light shielding layer formed in at least some region on an upper surface thereof and the light shielding layer is composed of at least one printed pattern, the printed pattern being composed of a single printed layer or multiple printed layers and having a first plane formed at a top portion thereof and an inclined angle θ of greater than about 0° to about 85° or less, the inclined angle being defined between the first polarizer protective film and an imaginary line I-II connecting one distal end point I of the first plane at the top portion of the printed pattern to a point II disposed on an outer peripheral surface of the printed pattern adjoining the first polarizer protective film and closest to the distal end point I.
