Abstract:
1. A high luminance polarizing plate comprising: a polarizing plate; a λ/2 retardation film laminated on one side of the polarizing plate; and a brightness enhancement film laminated on the λ/2 retardation film, wherein the λ/2 retardation film has an in-plane retardation value ranging from 250 nm to 280 nm in a wavelength range of 450 nm to 650 nm, wherein the λ/2 retardation film satisfies Equations (2) and (3) below, and wherein the brightness enhancement film is laminated to have a transmission axis disposed at an angle ranging from 85° to 95° with respect to the transmission axis of the polarizing plate and at an angle ranging from 40° to 50° with respect to the optical axis of the λ/2 retardation film, where R
