Abstract
The present invention discloses a backlight module and a liquid crystal device (LCD). The backlight module includes a LED component, a light guiding plate, a quantum dot (QD) layer, and a graphite sheet. The QD layer is arranged between the LED component and the light guiding plate, and the QD layer is arranged on the graphite sheet. By configuring the QD layer on the graphite sheet, the QD layer is prevented from being failed due to high temperature so as to extend the life cycle of the QD layer. Thus, the display performance may be enhanced.
