A backlight module includes three light emitting elements, an inverse prism sheet and a light guide assembly. The light guide assembly is disposed opposite to the inverse prism sheet and includes three light guide plates. A first surface of the first light guide plate opposite to the inverse prism sheet has a first sunken eye structure having a first long axis extending along a reference direction. A second surface of the second light guide plate opposite to the inverse prism sheet has a second sunken eye structure having a second long axis. A third surface of the third light guide plate opposite to the inverse prism sheet has a third sunken eye structure having a third long axis. Orthographic projections of the second long axis and the third long axis on the first surface are inclined towards two opposite sides of the reference direction.

Backlight module

The present invention provides a light guide plate having a light exit surface, a light incident surface and a bottom surface. In the said light guide plate, the bottom surface is opposite to the light exit surface, and the light incident surface connects the light exit surface and the bottom surface. A plurality of light guide structures are formed on the bottom surface, and each of the light guide structure includes a front mound protruding above the bottom surface, a back mound protruding above the bottom surface and located at the side of the front mound opposite to the light incident surface, and a concave eye-shaped portion caved in from the bottom surface and located between the front mound and the back mound. The concave eye-shaped portion has a first slope surface connected with the front mound and a second slope surface connected with the back mound, wherein the first slope surface and the second slope surface are connected at the bottom of the concave eye-shaped portion so as to form an arc-shaped connection border junction.
