Abstract

The present invention discloses a LED backlight module, which comprises a backplane; a side-type backlight source, which comprises a backlight source substrate and multiple light emitting diodes provided on the backlight light source substrate; a reflector, which is provided on the backplane; multiple light guides provided on the reflector in parallel, each light guide being provided with at least one light-incident surface and one light-emitting surface, the light-incident surface of the light guide being opposite to the LED; diffusers provided on the multiple light guides, which are opposite to the light-emitting surface of the light guide; and an optical film set, which is located above the diffuser. The embodiment of the present invention further discloses the corresponding liquid crystal display. According to the embodiment of the present invention, it can save the amount of LEDs, which is beneficial for the narrow frame of the liquid crystal display panel.
