Abstract:
A backlight module and a display device are provided. The backlight module includes a light source, a light guide plate and a reflection sheet. A side of the light guide plate includes a light-incident surface perpendicular to a bottom surface, a first inclined plane, and a second inclined plane. An intersecting line between a plane in which the first inclined plane lies and a plane in which the second inclined plane lies is located outside of the light guide plate, and the intersecting line is parallel with the bottom surface. The first and second inclined planes are configured such that a total reflection occurs on at least a part of the light at the first and second inclined planes, and thus an incidence angle of light emitted towards the bottom surface is greater than or equal to a critical angle at the bottom surface.

Claim (Index 13):
The backlight module of  claim 1 , wherein the luminous surface of the light source is parallel with the light-incident surface,\n an angle i 1  between the first inclined surface and the light-emergent surface satisfies a first angle formula of i 1 \u2265(i g \u2212i a )/2, wherein i 1  is the angle between the first inclined plane and the light-emergent surface, i g  is a critical angle of an interface between the bottom surface and the glue layer, i a  is a critical angle of an interface between the light-emergent surface and the air; a length L 1  of the first inclined plane in a direction perpendicular to the light-incident surface satisfies a first length formula of L 1 \u2265h 1 /tan \u03b1\u2212s, wherein L 1  is the length of the first inclined plane in the direction perpendicular to the light-incident surface, h 1  is a farthest distance of a luminous surface of the light source to the light-emergent surface in a direction perpendicular to the bottom surface, \u03b1=90\u00b0\u2212i g , and s is a vertical distance of the luminous surface of the light source to the light-incident surface.
