CIRCULARLY POLARIZING PLATE AND CIRCULARLY POLARIZING PLATE WITH GLASS PLATE

摘要

The purpose of the present invention is to provide: a circularly polarizing plate having good optical characteristics even after a wet heat test; and a circularly polarizing plate with a glass plate. This circularly polarizing plate has a linear polarizing layer, an attachment layer, and a λ/4 retardation layer in this order, wherein: the linear polarizing layer contains a cured product of a polymerizable liquid crystal compound and a dichroic dye; and the λ/4 retardation layer contains a cured product of a polymerizable liquid crystal compound. The moisture permeability of the attachment layer at a temperature of 40 °C and a humidity of 90%RH is 100 g/(m²∙24hr) or less.
