Claim 12:
13. A display device, comprising a display module, wherein the display module comprises:
a light guide plate, wherein the light guide plate comprises a light entering face and a light exiting face adjacent to each other;
a blue light source, disposed at the light entering face of the light guide plate; and
a display panel, disposed at a side of the light exiting face of the light guide plate;
wherein the display panel comprises a plurality of display units and a light shielding barrier wall which separates adjacent display units; each of the plurality of display units comprises a quantum dot unit, a liquid crystal unit, a transparent barrier wall and a first light shielding pattern, the quantum dot unit and the liquid crystal unit are arranged in parallel with each other along a lateral direction, the transparent barrier wall separates the liquid crystal unit from the quantum dot unit, and the first light shielding pattern is arranged at a side of the liquid crystal unit away from the light guide plate; an orthographic projection of the liquid crystal unit onto the light guide plate is located within an orthographic projection of the first light shielding pattern onto the light guide plate, and an orthographic projection of the quantum dot unit onto the light guide plate overlaps with an orthographic projection of a gap between adjacent first light shielding patterns onto the light guide plate.
