| description | The utility model discloses a backlight source and a display device. The backlight source of one embodiment comprises a light source and a light guide plate located on the light emitting side of the light source, and the light guide plate comprises a first side face away from the light source side. The side reflection film is located on the first side face, and the side reflection film forms a first projection on the first side face; the limiting piece comprises a first limiting part located on the first side face, and the first limiting part forms a second projection on the first side face; wherein the first projection and the second projection do not coincide. According to the embodiment of the utility model, the problem that the side reflection film is wrinkled and swelled due to friction between the side reflection film and the limiting piece after the light guide plate expands and deforms can be solved, so that the poor white spot of the backlight source is effectively improved, and the display performan |
