The utility model provides a kind of double-screen backlight module and display device, double-screen backlight module includes display back frame, it includes bottom plate, first side edge being set along longitudinal direction, and second side edge being set along transverse direction, bottom plate, first side edge and second side edge are formed around and form accommodating cavity;Light guide piece is set in accommodating cavity;First optical film component and second optical film component are located on light guide piece, and in transverse direction closely connect;First, second optical film component is equipped with first privacy film and second privacy film respectively, and respectively has first louver microstructure layer and second louver microstructure layer;With transverse direction as light transmission axis direction, the deflection angle of two louver microstructure layers is α and β respectively relative to light transmission axis direction in turn, and there is relational expression: β-α=90 °±10 °. Double-screen backlight module is by limiting the observation angle of first optical film component, inhibits the light interference of second optical film component, while reducing overall thickness and frame width.
