1. A display comprising:
- a liquid crystal display panel;
a light source; and
an asymmetric mirror positioned between the liquid crystal display panel and the light source to receive incident light generated by the light source, wherein the asymmetric mirror is operable to reflect incident light having a first polarization and partially reflect and transmit incident light having a second polarization different than the first polarization, wherein the asymmetric mirror has an average transmission of the first polarization of less than 20% and an average transmission of the second polarization of less than 50%.
