Abstract
A polarizing plate and an optical display apparatus including the same are provided. A polarizing plate includes a polarizer, and an optical functional layer on a light emission surface of the polarizer, and the optical functional layer includes a mixture of anisotropic particles and isotropic particles, the anisotropic particles include acicular particles, and the acicular particles are oriented in an in-plane direction of the optical functional layer, and when a light absorption axis of the polarizer is 0°, an average value of orientation angles formed between the light absorption axis of the polarizer and a longitudinal direction of the acicular particles is in a range from −10° to +10°, and a standard deviation of the orientation angles is 15° or less.
