Abstract:
1. A display device, comprising: A liquid crystal panel, and A multilayer optical film, the multilayer optical film located between the liquid crystal panel and an intended viewer, such that light incident upon the device is first incident upon the multilayer optical film, Wherein the multilayer optical film comprises UV stable material, such that the multilayer optical film is capable of sustainable outdoor use; wherein the film transmits over 60% of a short range visible band of light at a 60 degree angle of incidence through to the liquid crystal panel, and the film reflects an average of at least a majority of a large LC destructive band at a 60 degree angle of incidence; wherein the large LC destructive band is light of wavelengths between about 600 and 800 nm, and wherein the multilayer optical film reflects an average of at least about 75% of the LC destructive band at a 60 degree angle of incidence; And further wherein the film transmits over 70% of a long range visible band of light at normal incidence through to the liquid crystal panel.
