Abstract:
A backlight module includes: a light guide plate; a light source for emitting light rays towards a first region of the light guide plate; a first grating provided at the first region and configured to adjust propagation directions of the light rays such that the adjusted light rays travel towards a second region of the light guide plate, and the propagation directions make an included angle with a normal to the light guide plate which is greater than the critical angle of total reflection of the light guide plate; and a second grating provided at the second region and configured to collimate the adjusted light rays such that the collimated light rays travel in a direction perpendicular to the light guide plate.

Claim (Index 20):
The display device according to  claim 18 , wherein first sub-gratings of the plurality of first sub-gratings which are positioned in a same row parallel to a first sidewall of the light guide plate are configured to adjust the propagation directions of the light rays from corresponding light sources such that the propagation directions of the adjusted light rays are perpendicular to a second sidewall of the light guide plate, wherein the first sidewall is perpendicular to the second sidewall.
