Provided are an anti-reflective film, a polarizing plate comprising same, and an optical display device comprising same, wherein in the anti-reflective film, a base layer, a high-refractive layer, and a low-refractive layer are sequentially stacked, the low-refractive layer comprising inorganic hollow particles having an average particle diameter of about 70 nm to about 150 nm, the low-refractive layer comprising a single layer arrangement of the inorganic hollow particles.

Anti-reflective film having monolayer arrangement of inorganic hollow particles, polarizing plate comprising same, and optical display device comprising same

Provided is a liquid crystal display device having a viewing-side polarizing plate, a liquid crystal panel and a light source-side polarizing plate, which are stacked sequentially, wherein the viewing-side polarizing plate comprises a first polarizer and a first protective film formed on a light output surface of the first polarizer, the light source-side polarizing plate comprises a second polarizer and a fourth protective film formed on a light incident surface of the second polarizer, and the TD shrinkage ratio of the fourth protective film is greater than the TD shrinkage ratio of the first protective film.

Liquid crystal display device

A polarizing plate and an optical display including the same are provided. A polarizing plate includes: a polarizer; a bonding layer on an upper surface of the polarizer; and an anti-reflection film on an upper surface of the bonding layer, and the anti-reflection film includes a base layer, a high refractivity layer, and a low refractivity layer sequentially stacked on the bonding layer in the stated order, the bonding layer has an index of refraction of about 1.51 to less than 1.60, and the polarizer, the bonding layer, and the base layer satisfy the relation: Index of refraction of polarizer&#x3c;Index of refraction of bonding layer&#x3c;Index of refraction of base layer.

Polarizing plate and optical display comprising the same

A polarizing plate includes a polarizer; and a protective film attached to at least one side of the polarizer via an adhesive layer. The adhesive layer is formed of a water-based adhesive including a polyvinyl alcohol resin, a zirconium compound, and an imine crosslinking agent. The polarizing plate has a variation in light transmittance (|B&#x2212;A|) from 0% to about 0.25% at wavelengths from 400 nm to 780 nm, where A is an average value of initial light transmittance of the polarizing plate at wavelengths from 400 nm to 780 nm, and B is an average value of light transmittance of the polarizing plate at wavelengths from 400 nm to 780 nm measured after the polarizing plate has been dipped in water of 25&#xb0; C. for 3 hours, followed by drying at 25&#xb0; C. for 2 hours.
