1. A polarizing plate comprising:
a polarizer; and
a patterned portion comprising a first resin layer and a second resin layer stacked on at least one surface of the polarizer, the first resin layer having a different index of refraction from the second resin layer,
wherein the first resin layer is a patterned layer comprising: multiple first optical patterns formed at intervals at an interface with the second resin layer; and one or more second optical patterns formed between each pair of adjacent first optical patterns,
a first optical pattern of the multiple first optical patterns has two opposite side surfaces each at least comprising a first side surface having a base angle, and
the first optical pattern and a second optical pattern of the one or more second optical patterns satisfy the following Relations 1 to 3:
0.1 μm≤m2≤m1×0.2, (1)
0.1 μm≤w2≤w1×0.5, (2)
0.1 μm≤h2≤h1×0.2, (3)
where m1 is a minimum width (unit: μm) between the opposite first side surfaces of the first optical pattern,
w1 is a maximum width (unit: μm) between the opposite first side surfaces of the first optical pattern,
h1 is a minimum distance (unit: μm) between the minimum width and the maximum width of the first optical pattern,
m2 is a maximum width (unit: μm) of a second surface formed at a top portion of the second optical pattern,
w2 is a maximum width (unit: μm) of the second optical pattern, and
h2 is a maximum height (unit: μm) of the second optical pattern.
