Abstract: The disclosure discloses a circuit board, as well as a backlight module and a display device including the circuit board. The circuit board includes a copper exposure region which is covered with a conductive ink. By means of the copper exposure region and the conductive ink thereon, the function of conducting electrostatic charges for the circuit board can be realized at low cost in high efficiency, thereby reducing the risk of subjecting the electrical elements on the circuit board to electrostatic breakdown.

Abstract: Embodiments of the present disclosure provide a backlight module and a display apparatus. The backlight module includes: a light guide plate, including a first main surface and a second main surface being opposite to each other; and at least one light-emitting unit, arranged on a side of the first main surface of the light guide plate, wherein at least one groove is disposed on a side of the light guide plate positioned on the first main surface, and at least one light-emitting unit is arranged in each of the groove.
