Abstract
A backlight module and a liquid crystal display panel are provided. The backlight module includes a substrate, multiple light emitting diodes, a quantum dot layer, a light-shielding layer, and a heat dissipation structure. The substrate has a first surface and a second surface opposite to the first surface. The multiple light emitting diodes are disposed on the first surface. The quantum dot layer is disposed on one side of the multiple light emitting diodes facing away from the substrate. The multiple light emitting diodes are each configured to emit lights of a first color. The lights of the first color are of the first color, a second color, or a third color after passing through the quantum dot layer. The light-shielding layer is disposed between each two adjacent light emitting diodes. The heat dissipation structure is disposed on the second surface.
