Abstract: Disclosed herein are a backlight unit and a display apparatus. The backlight unit includes a light guide plate and a reflective polarizer. The reflective polarizer polarizes a first light to a first polarizing axis direction and reflects the first light, the first light being from a direction oblique to a front surface of the light guide plate. The reflective polarizer polarizes a second light to a second polarizing axis direction, which is different from the first polarizing axis direction, and transmits the second light, the second light being from a direction orthogonal to the front surface of the light guide plate.
