The thickness of the LED light bar is only one coin, and the LED light bar is light, so that only a very small space is required inside the display module 10 for installation. Referring further to fig. 5, the substrate portion 141 of the light source 14 is adhered to the first plane 131 of the light guide plate 13 by a heat conductive adhesive.
