The wavelength-converting device includes a transparent upper barrier film, a transparent lower barrier film, a spacer layer, a filling material and a plurality of quantum dots. The spacer layer is bonded between the transparent upper barrier film and the transparent lower barrier film, and has a plurality of hollowed regions. The filling material covers the plurality of hollowed regions. The plurality of quantum dots are uniformly distributed in the filling material covering each hollowed region. The light source includes a circuit board and a plurality of semiconductor light-emitting device. The circuit board is disposed beneath the transparent lower barrier film. Each hollowed region corresponds to at least one semiconductor light-emitting device. Each semiconductor light-emitting device is electrically bonded on the circuit board, and locates beneath the corresponding hollowed region."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Backlight apparatus","description":"The invention discloses a backlight apparatus including a wavelength-converting device and a light source.
