The invention provides a light bar structure, a backlight module and a display device. The light bar structure comprises a circuit board, a plurality of LEDs and a plurality of quantum tubes; the LEDs are disposed on the circuit board according to a preset sequence; the quantum tubes are in one-to-one correspondence with the LEDs. The light bar structure, the backlight module and the display device according to the technical scheme have the advantages that the mechanical strength of the quantum tubes can be improved at the premise of meeting the requirement on high color gamut by shortening the quantum tubes, cracking or breakage of the quantum tubes is avoided and maintenance cost of light bars is decreased.
