摘要

An intermediate image is formed inside a light guide member by a projection lens or the like, whereby a small optical system having a wide viewing angle and high performance is provided. At least one curved surface among curved surfaces forming an optical system is an opposite-sign curvature curved surface having an opposite-sign curvature point different in curvature depending on direction, whereby the optical system is placed in a satisfactory aberration correction state.
