A backlight module includes a light guide plate (LGP) and a light emitting unit. The LGP has a first surface, a second surface, a light incident surface, a first curved convex surface, a first plane, a second curved convex surface and a second plane. The first surface has a visual area. The second surface is opposite to the first surface. The light incident surface, the first curved convex surface, the first plane, the second curved convex surface, and the second plane connects the first surface and the second surface. The light incident surface connects the first plane and the second plane. The light emitting unit is disposed beside the light incident surface for emitting a light beam, wherein the light beam is capable of entering the LGP through the light incident surface, and being transmitted out of the LGP through the visual area of the first surface.
