A reflective sheet comprises a plurality of perforations for extending a plurality of light-emitting elements therein, the reflective sheet further comprises a central line passing through its center, at least one first dimming area, and at least one second dimming area, and the distance between the at least one first dimming area and the central line is smaller than the distance between the at least one second dimming area and the central line. The light-emitting elements are distributed in the at least one first dimming area and the at least one second dimming area, the at least one first dimming area has a first dimming means, the at least one second dimming area has a second dimming means, the dimension of the first dimming means is different from the dimension of the second dimming means. Through the structural design of the reflective sheet, the luminance difference between the first dimming area and the second dimming area can be reduced, and the uniformity of the brightness in the whole area (Area Scan) can be improved. This invention also provides a backlight module and a display device including the reflective sheet.
