Abstract
A backlight module includes a light-emitting element, which can emit a first light with a wavelength in a first wavelength range, a quantum dot diaphragm, which is formed by combining a plurality of sub-diaphragms each with a small area together and can emit a second light with a wavelength in a second wavelength range and a third light with a wavelength in a third wavelength range, and a diffusing plate used for light homogenization. The defects of low qualified rate of quantum dot diaphragm with large area manufactured currently and a poor homogeneity thereof can be avoided.
