Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a composite polarizing plate which has an optical compensation plate including aligned liquid crystalline materials, and prevents the optical compensation plate from being cracked even under the change in environmental temperature. SOLUTION: A polarizing plate 11, a first adhesive layer 21, an optical compensation plate 12, and a second adhesive layer 22 are stacked in this order to obtain a composite polarizing plate 30. The optical compensation plate 12 has the liquid crystalline materials aligned therein, and has a tensile modulus of elasticity of ≤1,200N/mm2. Between the first adhesive layer 21 and the optical compensation plate 12, a retardation plate 13 and a third adhesive layer 23 may be disposed in this order from the side of the first adhesive layer 21.
