Circular polarizing plate and circular polarizing plate with glass plate

摘要

An object of this invention is to provide the circularly-polarizing plate which has favorable optical properties even after a wet-heat test, and a circularly-polarizing plate with a glass plate. The circularly polarizing plate of the present invention has a linearly polarizing layer, a bonding layer, and a λ/4 phase difference layer in this order, and the linearly polarizing layer contains a cured product of a polymerizable liquid crystal compound and a dichroic dye, and includes a λ/4 phase difference A layer contains the hardened|cured material of a polymeric liquid crystal compound. The water vapor transmission rate in the temperature of 40 degreeC of the bonding layer and 90%RH of humidity is 100 g/(m*24hr) or less.
