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 19):
The display device according to  claim 18 , wherein the first grating comprises a plurality of grating sets, each corresponding to one said light source and comprising a plurality of sub-gratings arranged in matrix,\n wherein the sub-gratings each adjust the propagation directions of the light rays emitted from corresponding light sources, respectively, such that the adjusted light rays travel towards the second region of the light guide plate, and the propagation directions make an included angle with the normal to the light guide plate which is greater than the critical angle of total reflection of the light guide plate.
