Abstract

A backlight module includes a substrate provided with a light-emitting region and a bonding region, a plurality of light-emitting units disposed on a side of the substrate, a back plate disposed on the other side of the substrate, and at least three drive circuit boards bonded and connected to the bonding region by first connectors. Moreover, an extension direction of a long edge of each of the light-emitting units is not parallel to a bonding edge of the bonding region. In this way, when the back plate is a curved back plate, the risk of peeling of the light-emitting units from the substrate when the back plate is in a curved state can be reduced by flexibly setting the degree of the included angle between the extension direction of each long edge of each light-emitting unit and the bonding edge of the bonding region.
