Abstract: A display device includes a display panel, a backlight module and a reel. The backlight module faces the display panel and includes a light transmissive region, a light emitting region and a peripheral region, in which the peripheral region is disposed between the light transmissive region and the light emitting region. The light transmissive region includes a first edge extending along a first direction and a second edge extending along a second direction. The backlight module includes a first brightness enhancing film including first microstructures arranged along the first direction. The first microstructures that pass through the peripheral region without connecting to the first edge have less light gathering efficiency than the first microstructures that only pass through the light emitting region. The reel faces the light transmissive region, and the display panel and the reel are respectively located on opposing sides of the backlight module.
