摘要：
A stereoscopic image observation optical-element includes: a laminated member including a λ/4 phase-difference member and a polarizing member. The λ/4 phase-difference member is provided on a light incidence surface side and has a slow axis in a first direction, and the polarizing member is provided nearer to a light emission side than the λ/4 phase-difference member and has a transmission axis in a direction crossing the first direction at substantially 45 degrees. The laminated member has a curved shape projecting to the light incidence surface side, and the λ/4 phase-difference member is configured of a material having a photoelastic coefficient of less than about 80*10−12/Pa.
