DISPLAY DEVICE HAVING WAVELENGTH CONVERTING LAYER

摘要

PURPOSE: A display device with a wavelength conversion layer is provided to output stable brightness and color coordinates of a light source according to a current and to effectively operate the display device. CONSTITUTION: A display device with a wavelength conversion layer(130) comprises a substrate(110), a light emitting element(120), and a first light source. The light emitting element is mounted on the substrate and emits lights of a first wavelength band. The first light source includes the wavelength conversion layer. The wavelength conversion layer is arranged on the light emitting element, absorbs at least some of the light of the first wavelength band, and converts the absorbed light into light of a second wavelength band.
