Abstract: A primary object of the present invention is to provide a polarizing plate excellent in durability. A polarizing plate (100) according to an embodiment of the present invention includes: a polarizer (10); and a protective film (21 and 22) arranged on at least one side of the polarizer (10). The polarizing plate (100) has a dimensional change ratio of −0.2% or more in a transmission axis direction thereof when the polarizing plate (100) cut into a size measuring 100 mm by 100 mm is bonded to a glass plate with a pressure-sensitive adhesive and the following operation is repeated 100 times: the polarizing plate (100) bonded to the glass plate is left to stand under an atmosphere at −40° C. for 30 minutes and then left to stand under an atmosphere at 85° C. for 30 minutes.

Abstract: Provided is an image display mirror that includes a half mirror and an image display apparatus, reduces an influence of a reflected image provided by the half mirror, and is excellent in visibility of an image displayed on the image display apparatus. The image display mirror for a vehicle includes: a circularly polarizing plate arranged attachably and removably; a half mirror; and an image display apparatus in the stated order from a viewer side. In one embodiment, attached and removed states of the circularly polarizing plate are switched when an image is displayed on the image display apparatus and when the image is not displayed thereon, and when the image is displayed, the circularly polarizing plate is arranged between the half mirror and a viewer.
