The invention discloses a light guiding plate. The light guiding plate comprises a bottom surface and a light exiting surface, wherein the light exiting surface is opposite to the bottom surface and is recessed to form a groove (2211); the groove (2211) is filled with a plurality of luminous quantum dots (231); and a closing diaphragm (240) covers the light exiting surface so that the luminous quantum dots (231) are sealed in the groove (2211). The invention also discloses a backlight module with the light guiding plate and a liquid crystal display with the backlight module. The groove is formed in the light exiting surface of the light guiding plate and is filled with the luminous quantum dots (231), the color gamut of display backlight can be increased by the luminous quantum dots (231), the luminous quantum dots (231) surround side walls of the periphery of the groove, so that the light guiding plate can be thinned to the maximum extent, and a narrow frame design of the backlight module is easy to implement.
