A backlight module and a display panel are provided. The backlight module includes a light guide plate, a plurality of nanostructures, a plurality of dot structures, and a light source. The light guide plate includes a plate body. The plate body includes glass. The plate body includes a first surface, a second surface, and a first side surface, and the first surface is opposite to the second surface. A plurality of nanostructures are disposed on the first surface of the plate body, and a plurality of dot structures are disposed on the second surface of the plate body. A light source is disposed on the first side surface of the plate body. The light guide plate of the backlight module has a plurality of nanostructures and a plurality of dot structures, which makes thickness of the display device to be thin and increases light penetrability to improve screen brightness.
