摘要：
The optical film laminate comprises: a polarizing film which is formed of a polyvinyl alcohol-based resin containing a molecularly-oriented dichroic martial, and has a thickness of 10 μm or less; and a transparent protective film formed of a thermoplastic resin and disposed on one of opposite surfaces of the polarizing film through an adhesive layer. The transparent protective film has a thickness of 40 μm or less, and a dimensional change rate in a direction orthogonal to an absorption axis of the polarizing film is 0.2% or more, as measured using a test piece thereof having a size of 100 mm×100 mm, in a state after leaving the test piece in an environment at 85° C. for 48 hours.
