Abstract
A head-mounted display including a first optical system is described. The first optical system includes a partial reflector and a multilayer reflective polarizer disposed adjacent to and spaced apart from the partial reflector. The multilayer reflective polarizer is curved about orthogonal first and second axes and includes at least one layer that is substantially optically uniaxial at at least one location. Each chief ray that passes through the first optical system is first incident on the multilayer reflective polarizer at an angle of incidence less than 30 degrees.
