Side light emitting quantum dot lens, backlight module and quantum dot lens manufacturing method

The invention belongs to the technical field of backlight of display devices, and particularly relates to a side light emitting quantum dot lens, a backlight module and a quantum dot lens manufacturing method. Comprising a lower lens, a quantum dot fluorescent resin layer is arranged on the outer side face of the lower lens, a groove is formed in the bottom face of the lower lens, a reflecting mirror is arranged on the top face of the lower lens, and an upper lens is arranged above the lower lens and the reflecting mirror in a covering mode. The outer side face of the lower lens is directly coated with the quantum dot fluorescent resin, the quantum dot fluorescent resin material is saved, and the problems that the quantum dot lens is poor in consistency and secondary light distribution white spots cannot be dispersed are solved; in addition, the quantum dot fluorescent resin layer is arranged between the upper lens and the lower lens in a sealed mode, and good waterproofness is achieved. 本发明属于显示装置的背光技术领域，具体涉及
