Abstract
A virtual image display device includes a polarization adjustment member that includes a polarizing plate and a support plate. The polarizing plate has a property of blocking a light which is oscillated in an axial direction of a block axis while the polarizing plate is in a state where a residual stress, a degree of which is maximized in a first residual stress direction along a plane of the polarizing plate, is left in the polarizing plate. The support plate supports the polarizing plate while the support plate is in a state where a residual stress, a degree of which is maximized in a second residual stress direction along a plane of the support plate, is left in the support plate. The polarizing plate and the support plate are bonded together such that the first residual stress direction is along the second residual stress direction.
