Abstract
Some embodiments of the present disclosure disclose an LED backlight module and a display device, a plurality of light-emitting units are distributed on a substrate of the LED backlight module, and the surface of the substrate is provided with a plurality of solder mask window areas for the plurality of light-emitting units to abut against, and a conductive circuit connecting two adjacent light-emitting units includes a main circuit and an auxiliary circuit; a remaining portion of the substrate except for the solder mask window area is coated with an insulating material, an alignment error in the coating process causes the reserved solder mask window area to be covered and an actual solder mask window area to shift, since the auxiliary circuit passes through the solder mask window area and a routing-wiring direction is intersected the connecting-wiring direction of the two electrodes of the light-emitting units.
