| description | The utility model provides a backlight module which is used for providing an illumination light beam. The backlight module comprises a light source and a light guide element. The light source provides light beams. The light guide element is disposed on a transmission path of the light beam. The light guide element comprises a plate body and a plurality of cylindrical surface units. The plate body has a top surface, a bottom surface, a side surface and a light incident surface. The top surface and the bottom surface are arranged back to back. The side surface and the light incident surface are arranged back to back. The light incident surface is connected between the top surface and the bottom surface. The light source is disposed on the incident surface. The plurality of cylindrical surface units are located on at least one of the top surface and the bottom surface of the plate body, each cylindrical surface unit extends along a first direction, and a first included angle is formed between the first direction |
