A head-mounted display including a first optical system is provided. The first optical system includes an image surface, a stop surface, a first optical stack disposed between the image surface and the stop surface and a second optical stack disposed between the first optical stack and the stop surface. The first optical stack includes a first optical lens and a partial reflector. The second optical stack includes a second optical lens and a curved multilayer reflective polarizer. A quarter wave retarder is disposed between the multilayer reflective polarizer and the partial reflector. The multilayer reflective polarizer and the partial reflector may be convex toward the image surface along orthogonal first and second axes.
