Virtual image display apparatus


A light guide member (10) includes three surfaces of a second surface (s12), a fourth surface (s14), and a fifth surface (s15) as two or more non-axisymmetric curved surfaces, and a projection lens (30) includes a lens surface (31a) as a non-axisymmetric aspheric surface. With this, on the light guide member side, even when there is a shape constraint that the first surface (s11) or the third surface (s13) which is a surface contributing to light guide is a flat surface, and correction of asymmetric aberration is limited, it becomes possible to perform sufficient aberration correction as the whole of an optical system including the projection lens.
