摘要:
A polarizing plate includes a polarizer, a first protective film attached to one side of the polarizer, and a second protective film attached to another side of the polarizer. A ratio between coefficients of thermal expansion of the first and second protective films, measured in a transverse direction (TD) at a temperature from about 25° C. to about 120° C., ranges from about 0.5 to about 2. A ratio between coefficients of thermal expansion of the first and second protective films measured in a machine direction (MD) at a temperature from about 25° C. to about 120° C. ranges from about 0.5 to about 2.
摘要:
Provided are a host material for a blue phosphor, and an organic thin film and an organic light-emitting device including the same. The host material for a blue phosphor is such that a carbazole compound is bonded around a central atom, wherein the central atom is a Group 14 element, and the carbazole compound bonded around the central atom is 3 or 4, wherein the carbazole compound includes carbazole in which an alkyl group is substituted. The host material for a blue phosphor has high triplet energy (ET) and excellent electrical mobility and thermal stability. As a result, the organic thin film, which includes the host material, and the organic light-emitting device, which includes the organic thin film, implement a deep blue color and have excellent luminous efficiency.

摘要:
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−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° C. for 3 hours, followed by drying at 25° C. for 2 hours.
