A display device includes a light source, a spatial light modulator, and an optical assembly. The light source is configured to provide illumination light and the spatial light modulator positioned to receive the illumination light. The optical assembly includes an optical element and a curved reflector that is distinct and separate from the optical element. The curved reflector is disposed relative to the light source so that at least a portion of the illumination light is reflected by the curved reflector toward the optical element, is reflected by the optical element toward the curved reflector, and is transmitted through the curved reflector. A method performed by the display device is also disclosed.
