Polarizing plate and liquid crystal display device including same
Provided are a polarizing plate and a liquid crystal display device including same, the polarizing plate including a polarization film, a contrast-improving layer, and an anti-reflection film that are sequentially laminated. The minimum reflectance of the anti-reflection film is no greater than 0.45%. The anti-reflection film has a first substrate layer, a high-refraction layer and a low-refraction layer that are laminated in order from the contrast-improving layer. The contrast-improving layer includes a first resin layer and a second resin layer facing the first resin layer. The second resin layer is provided with a pattern part having optical patterns and a flat part between the optical patterns. The pattern part satisfies Equation 1 and the optical patterns have a base angle (θ) of 75° to 90°. The slope of the reflectance of the polarization plate in Equation 2 is no greater than 0.3.
