Abstract
A light emitting optical film at least including a substrate, an alignment layer and a polarized light emitting liquid crystal film is provided, in which the polarized light emitting liquid crystal film includes liquid crystal and light-emitting dye. The alignment layer is located on one side of the substrate, and the polarized light emitting liquid crystal film is located on the alignment layer. The light emitting optical film can be applied to polarizing film, phase retardation film or color filter. Moreover, it is unnecessary to use conventional backlight module because overall arrangement of liquid crystal can fully emit uniform polarized light, whereby greatly reducing cost of conventional backlight module.
