Abstract
A display device includes a substrate, a plurality of white light-emitting units, and a color filter layer. The white light-emitting units are arranged on the substrate at intervals, and the white light-emitting units are chip scale package (CSP). The color filter layer is above the white light-emitting units. Each of the white light-emitting units includes a light-emitting diode chip and a wavelength conversion film. The wavelength conversion film directly covers a top surface and side surfaces of the light-emitting diode chip, and the wavelength conversion film converts light emitted by the light-emitting diode chip into white light.
