| titleOfInvention | polarizing film |
| abstract | A polarizing film in which a transparent protective film or an optical function film is bonded to at least one surface of a polarizing film, wherein the polarizing film is formed by adsorbing and orienting iodine to a polyvinyl alcohol-based film, and has an iodine concentration of more than 10% by weight, and the transparent polarizing film The protective film or the optical function film is a first film having a water vapor transmission rate of 200 g/(m 2 ·24h) or less, and the polarizing film has a single transmittance of 41% or less, and the general formula (1): ΔTs (%) = Ts 96 - A polarizing film that satisfies the condition that the amount of change in single transmittance (ΔTs) represented by Ts 0 is 0% or more and 5% or less. The polarizing film has an initial single transmittance of 41% or less in a polarizing film having a high iodine content, and is excellent in suppressing a decrease in single transmittance due to coloring of the polarizing film in a high-temperature environment, and also in a high-temperature, high-humidity environment. It is excellent in the effect of suppressing the decrease in polarization degree (humidification durability). |
