Abstract
A display device includes a substrate, a first light emitting element, a second light emitting element, and an optical film sheet. The first light emitting element and the second light emitting element are disposed on the substrate. The first light emitting element emits a first light, and the first light has a first wavelength range. The second light emitting element emits a second light, and the second light has a second wavelength range. The optical film sheet is disposed above the first light emitting element and the second light emitting element. The optical film sheet includes a first zone and a second zone. The first zone includes a first cholesteric liquid crystal, and the first cholesteric liquid crystal reflects light in at least the first wavelength range. The second zone includes a second cholesteric liquid crystal, and the second cholesteric liquid crystal reflects light in at least the second wavelength range.
