A reflective sheet includes a first reflective layer and a second reflective layer. The first reflective layer has a first index of refraction, and the second reflective layer has a second index of refraction. The first reflective layer and the second reflective layer are in contact with each other to form a contact interface, and the first index of refraction is different from the second index of refraction so as to make the contact interface be a reflective surface. A top surface of the first reflective layer opposite the contact interface serves as a light incident surface for the reflective sheet, the reflectance of the first reflective layer is larger than the reflectance of the second reflective layer, and the mechanical strength of the second reflective layer is larger than the mechanical strength of the first reflective layer.
A reflective sheet, comprising:
A reflective sheet adapted to a backlight module having a light guide plate, the reflective sheet comprising a first reflective layer and a second reflective layer, wherein the first reflective layer and the second reflective layer are made from different materials and in contact with each other to form a contact interface, the contact interface is a reflective surface, a top surface of the first reflective layer opposite the contact interface touches a plurality of light-scattering dots of the light guide plate, the reflectance of the first reflective layer is larger than the reflectance of the second reflective layer, and the mechanical strength of the second reflective layer is larger than the mechanical strength of the first reflective layer.
