Beschreibung
Zusammenfassung:	A display device includes a substrate, a first light emitting element, a second light emitting element and an optical film. 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 is disposed above the first light emitting element and the second light emitting element. The optical film includes a first zone and a second zone. The first zone includes first cholesteric liquid crystals which reflect a light in at least the first wavelength range. The second zone includes second cholesteric liquid crystals which reflect a light in at least the second wavelength range.
