Abstract
The invention provides a liquid crystal display device, a liquid crystal display module and a liquid crystal cell thereof. The liquid crystal cell includes an upper substrate, a lower substrate, and a mixture of a quantum dot material and a liquid crystal material disposed between the upper substrate and the lower substrate. The quantum dot material includes a red quantum dot material and a green quantum dot material. A mass ratio of a total mixing amount of the two quantum dot materials occupied in a total mass of the mixture is 0.05˜5 wt %. As to the liquid crystal cell, the introduction of the QD material promotes the directional arrangement of liquid crystal molecules and thus plays a role of alignment; in another aspect, the liquid crystal cell being used in conjunction with a backlight source of blue or white LED can enhance the color gamut.
