Abstract: A display may include a display panel that emits light. The light from the display panel may be focused by a lens assembly towards a viewer. A light redirecting layer may be included in the display between the display panel and the lens assembly to ensure that the lens assembly receives incident light at an optimal angle. The light redirecting layer may redirect light by different amounts at different portions of the light redirecting layer. The magnitude of the redirection angle may increase with increasing separation from the center of the light redirecting layer. The light redirecting layer may redirect light away from the center of the light redirecting layer. The light redirecting layer may be a geometric phase lens formed using a liquid crystal film. The display may also include a circular polarizer, an additional circular polarizer, and an additional quarter waveplate.
