Abstract
Provided are a backlight module, a manufacturing method thereof and a display device. The backlight module includes: a light-transmitting substrate; light sources and a first film layer located on a same side of the substrate; and a first metal layer located on a side of the first film layer away from the substrate. The light source includes a light-emitting surface and an electrode located on two opposite sides of the substrate. A distance between a surface of the first film layer away from the substrate and the substrate is greater than that between a surface of the electrode away from the substrate and the substrate. The first film layer is provided with a first recess, and the first recess exposes at least part of the electrode. The first metal layer includes a connection electrode, and the connection electrode is connected with the electrode in the first recess.
