Provided are a polarizer protection film, a polarizing plate comprising the same, and a liquid crystal display device comprising the polarizing plate. The polarizer protection film has: a moisture permeability ranging from approximately 0 g/m/24 hr to approximately 100 g/m/24 hr; a value for a MD-direction shrinkage rate/a TD-direction shrinkage rate, ranging from 0.8 to 1.3; an in-plane phase difference (Re) ranging from approximately 0 nm to approximately 350 nm; a thickness-direction phase difference (Rth) ranging from approximately 2500 nm to approximately 8000 nm; and a thickness of approximately 10 &#x3bc;m to approximately 60 &#x3bc;m.

Polarizer protection film, polarizing plate including same, and liquid crystal display device including polarizing plate

An optical film, an organic light-emitting diode (OLED) display, and a method of fabricating an OLED display are provided. An optical film includes: a polarizer; and a protective film on at least one surface of the polarizer, and an in-plane retardation of the protective film is from 0 nm to 300 nm, and a reflectance of the optical film is from 0 to 5%.

Optical film and OLED display having the same

An optical film, a liquid crystal display including the same, and a method for manufacturing a protective film used therefor are provided. An optical film includes a polarizer and a protective film laminated or stacked on at least one surface of the polarizer, and a thickness-direction retardation (Re) of the protective film is in the range of 0 nm to 200 nm, and an out-of-plane retardation (Rth) of the protective film is in the range of 300 nm to 1,200 nm.

Optical film, liquid crystal display device comprising same, and method for manufacturing protective film used therefor

Disclosed are an optical film, a method for preparing the same, and a liquid crystal display including the same. The optical film is a single film of a non-liquid crystalline thermoplastic resin, and includes: first and second surface part placed on both surfaces of the film in a thickness direction; and an inner part of the film placed between the first and second surface part, wherein the first and second surface part are not aligned with a tilt in the thickness direction, and the inner part of the film is aligned with a tilt in the thickness direction.

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.
