Claim 0:
1. A polarizing plate comprising:
a polarizer; and
a pattern layer disposed on an upper surface of the polarizer,
wherein the pattern layer comprises a first resin layer, the first resin layer being formed on a lower surface thereof with at least one engraved pattern having a lateral side, the lateral side having a first facet and a second facet consecutive to the first facet, the first facet and the second facet having different base angles with respect to a maximum width of the engraved pattern and satisfying Relations 1 and 2:

θ1>θ2,  [Relation 1]

wherein Relation 1, θ1 denotes a base angle of the first facet, θ2 denotes a base angle of the second facet, about 70°≤θ1≤about 90°, about 0°<θ2<about 90°; and

about 0.5≤h1/(h1+h2)<about 1.0,  [Relation 2]

wherein Relation 2, h1 denotes a projection height of the first facet projected on a maximum height of the engraved pattern and h2 denotes a projection height of the second facet projected on the maximum height of the engraved pattern.
