Abstract
The present invention provides a backlight module and display panel. The backlight module includes a light guiding plate, an optical film, and at least two positioning structure. The at least two positioning structure are placed on the opposite side surfaces of the light guiding plate. Each of the positioning structure includes a main positioning member and a sub positioning member fixedly connected to the main positioning member. The main positioning member is fixedly connected to the side surface of the light guiding plate. The sub positioning member extends for a fixing distance along the main positioning member. The opposite at least two sub positioning member fix the optical film on the emitting surface of the light guiding plate.
Claims18
