Abstract
Disclosed are a backlight module and a display device. The backlight module includes a driving backplate and an optical film on a side of the driving backplate light taking-off. The driving backplate includes a substrate, electronic elements, and an adhesive layer. The electronic elements are disposed on a side of the substrate close to the optical film. The adhesive layer covers the electronic elements and includes first adhesive-dispensed portions. The first adhesive-dispensed portions are in contact with the optical film.
