Abstract
An electronic mirror device includes: a liquid crystal panel that displays an image; a linearly reflective polarizing layer that transmits a polarization component of incident light in a first direction and reflects a polarization component of the incident light in a second direction different from the first direction; a glass that transmits the incident light; and a PET film bonded to the glass. The linearly reflective polarizing layer is disposed between the liquid crystal panel and the PET film. The PET film contains polyethylene terephthalate and has a retardation value in a range of 2000 nm or more and 4000 nm or less. An angle between a slow axis of the PET film and a polarization reflection axis of the linearly reflective polarizing layer is 30 degrees or more and 60 degrees or less.
