The invention relates to a backlight module, which comprises a light guide plate, at least one first polarized light source and at least one second polarized light source. The first polarized light source which emits first polarized light is arranged at a position on a first side surface adjacent to the light guide plate. The second polarized light source which emits second polarized light is arranged at a position on a second side surface adjacent to the light guide plate. The light guide plate comprises a first polarized light active zone and a second polarized light active zone, wherein the first polarized light active zone is adjacent to the second polarized light source, the second polarized light active zone is adjacent to the first polarized light source, the first polarized light active zone is used for reflecting the second polarized light and allowing the first polarized light to penetrate, and the second polarized light active zone is used for reflecting the first polarized light and allowing the s
