Abstract
The disclosure provides a quantum dot light source device, a backlight module, and a liquid crystal display device, where the quantum dot light source device includes an upper substrate, a lower substrate, and a quantum dot material layer packaged between the upper substrate and the lower substrate, and reflection points are arranged on the upper substrate so that the reflectivity of light rays by the reflection points at the center of the upper substrate is higher than the reflectivities of the light rays at the peripheral edges thereof.
