Abstract
The present disclosure describes a liquid crystal display device. The liquid crystal display device includes a substrate and a plurality of light sources disposed on the substrate and configured to generate excitation light. The liquid crystal display device includes a quantum dot film disposed in a light-emitting direction of the plurality of light sources and a plurality of stereoscopic reflecting plates disposed on the substrate. The liquid crystal display device includes an optical layer disposed between the plurality of light sources and the quantum dot film. The plurality of stereoscopic reflecting plates and the plurality of light sources form a plurality of cavities arranged in an array. The plurality of light sources are located on bottoms of the plurality of cavities respectively. The optical layer is disposed between the plurality of cavities and the quantum dot film, and configured to partially transmit and partially reflect the excitation light. The quantum dot film is configured to be excited by the excitation light to generate excited light.
