The invention discloses a backlight lamp bar, a backlight module, and a display device, and belongs to the technical field of display. The backlight lamp bar includes a flexible circuit board and backlight lamps arranged on the flexible circuit board; the flexible circuit board includes a circuit board basal body and a static shielding structure arranged on a non-edge region of the circuit board basal body; and the static shielding structure and the backlight lamps are positioned on an opposite surface of the circuit board basal body. The invention solves the problem that the backlight lamp bar is poor in static resistance, and the backlight module is poor in static resistance, can improve the static resistance of the backlight lamp bar and the backlight module. The backlight lamp bar is used for the backlight module.
