Zusammenfassung:	According to the LED backlight module and the display screen, the top face and the side face of a carrier of a light-emitting unit adopted by the LED backlight module can transmit light, so that the light-emitting unit can emit light from multiple directions and multiple faces, the light-emitting angle and the light-emitting effect of the light-emitting unit can be greatly improved, and the light-emitting effect of the light-emitting unit can be greatly improved under the condition that the front face of a circuit board has the same light-emitting area. A smaller number of light-emitting units can be arranged, so that the cost of the LED backlight module is reduced; the light emitting normal direction of the main light emitting face of the light emitting unit is perpendicular to the normal direction of the circuit board, the light emitting unit can emit light from multiple directions and multiple faces, the light emitted by the light emitting unit is emitted from the light emitting face of the LED backlight m
