Summary:To provide a thin polarizing plate with a retardation layer which offers superior high-temperature durability.SOLUTION: A polarizing plate with a retardation layer according to an embodiment of the present invention comprises a polarizing plate including a polarizer containing 11 wt.% or more boric acid, and a retardation layer, or a liquid crystal compound alignment fixed layer, and is rectangular. A long-side direction of the polarizing plate with the retardation layer is orthogonal to a slow axis direction of the retardation layer.SELECTED DRAWING: Figure 1 【課題】優れた高温耐久性を有する薄型位相差層付偏光板を提供すること。【解決手段】本発明の実施形態の位相差層付偏光板は、ホウ酸含有量が１１重量％以上である偏光子を含む偏光板と、液晶化合物の配向固化層である位相差層と、を有する矩形の位相差層付偏光板であって、該位相差層付偏光板の長辺方向と該位相差層の遅相軸方向とが直交である。【選択図】図１
