The embodiment of the disclosure provides a light guiding plate comprising two light input surfaces at the two lateral sides, a light output surface at the top side and a scattering surface at the bottom side, scattering nodes are disposed on the scattering surface, and the scattering surface concaves toward the light output surface. The embodiment of the disclosure further provides a display module, comprising a display panel a backlight unit. The backlight unit comprises the light guiding plate, and LED modules disposed at the two opposite sides of the light guiding plate. The backlight of the light guiding plate is more uniform and the backlight effect is improved because light can enter the structure at the two sides as well as the scattering surface of the bottom side concaves toward the light output surface.
