Reflective element

A reflective element, adapted to a backlight module, wherein the backlight module comprises a plurality of light-emitting elements, and the reflective element comprises:

• a body, provided with a top surface, a bottom surface, and a plurality of light source grooves, wherein the top surface is opposite to the bottom surface, each of the light source grooves is provided with a light outlet, a bottom, and a reflective portion, the light outlets are formed on the top surface, the bottoms are opposite to the light outlets and are adapted to arrange the light-emitting elements, the reflective portions are located between the light outlets and the bottoms and are adapted to surround the light-emitting elements, each of the reflective portions comprises a first reflective surface and a second reflective surface, the first reflective surface is located between the second reflective surface and the bottom, and the second reflective surface is located between the first reflective surface and the light outlet;
• wherein a slope of the first reflective surface relative to the bottom surface is different from a slope of the second reflective surface relative to the bottom surface, or a curvature of the first reflective surface is different from a curvature of the second reflective surface.
