Liquid crystal display device comprising a blue light source and a quantum-dot colour generating structure and method of manufacturing said device

摘要

A liquid crystal display device and a method of manufacturing it are provided. The display device includes a blue light backlight source (1) and a liquid crystal display panel (2), wherein the liquid crystal display panel comprises a first substrate (22) and a second substrate (21). The first substrate or the second substrate includes a layered assembly, functioning as a colour filter and including a black matrix pattern (201), a red pixel pattern (202) and a green pixel pattern (203), wherein the red pixel pattern and the green pixel pattern are quantum dot material thin-film patterns respectively emitting red light and green light upon excitation by blue light. The red pixel pattern (202) is separated from the black matrix pattern (201) by an intervening first passivation layer (241); furthermore, the red and green pixel patterns are mutually separated by an intervening second passivation layer (242), and the green pixel pattern (203) is covered by a protection layer (243).
