Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a polarizing plate excellent in light characteristics and durability.SOLUTION: A polarizing plate contains a polarizer and a resin layer formed on at least one surface of the polarizer. A tensile strength in a direction (TD direction) perpendicular to a stretching direction of the polarizer at 5°C is 3-5 N/mm, the tensile strength at 80°C is 1-2 N/mm, and the polarizing plate is excellent in light characteristics and durability. An image display device includes the same.SELECTED DRAWING: Figure 1 【課題】光特性及び耐久性に優れた偏光板を提供すること。【解決手段】本発明は、偏光子及び前記偏光子の少なくとも一面に形成される樹脂層を含み、前記偏光子の延伸方向に垂直な方向（ＴＤ方向）における引張強度が、５℃において３〜５Ｎ／ｍｍであり、８０℃において１〜２Ｎ／ｍｍであって、光特性及び耐久性に優れた偏光板、並びにそれを備えた画像表示装置に関する。【選択図】図１
