Abstract: Disclosed are a backlight module and a display device. The backlight module includes a plurality of light-emitting units disposed at intervals with one another, an optical film, and a concentrating structure. A slit is between two adjacent light-emitting units. The optical film is disposed at a side of the light-emitting unit. The concentrating structure is disposed at a side of the optical film close to the light-emitting unit and arranged in an area opposite to the slit. The concentrating structure comprises a plurality of protrusions.

Abstract: An optical film layer and a manufacturing method thereof, a polarizer, and a display panel are provided. The optical film layer includes a base layer and a group of particle layers arranged in the base layer. The group of particle layers includes multiple particle layers, and refractive indices of the multiple particle layers gradually decrease in a direction from a first side of the optical film layer to a second side of the optical film layer.
