Abstract
A quantum dot lens, a backlight module, a display device and a manufacturing method of the quantum dot lens are provided. The quantum dot lens includes: a first lens, which is a convex lens and is provided with a first lens surface; a second lens, which is a concave lens and is provided with a second lens surface opposite to the first lens surface; and a quantum dot fluorescent resin layer, provided between the first lens surface and the second lens surface, and including more than one quantum dot fluorescent material. With the above structure, the quantum dot lens has a simple manufacturing process and ease of mass production, saves the quantum dot fluorescent material, and solves the problems of poor consistency and blue light leakage of existing quantum dot lenses.
