Abstract:
The present disclosure provides a light guide plate, a manufacturing method thereof, a backlight source and a display device. The light guide plate includes: a first surface, a second surface, and at least one blazed gating structure that is on the second surface of the light guide plate, wherein light incident from the first surface of the light guide plate forms a total reflection in the light guide plate after the light irradiates the at least one blazed gating structure and is diffracted by the at least one blazed grating structure.

Claim (Index 12):
The light guide plate according to  claim 1 , wherein the light incident from the first surface exits from the blazed grating structure, and the light exits from the blazed grating structure incident to the surface of the light guide plate at an angle \u03c6, \u03c6 c  is a total reflection critical angle of the light guide plate, \u03c6 being not smaller than \u03c6 c ,\n \u03a6 c =arc sin (1/n) and \n 2d sin \u03b8 cos (\u03b1\u2212\u03b8)=k\u03bb, \n where n is a refractive index of a material of the light guide plate, \u03b1 is an angle between the incident light and a macro plane normal of the blazed grating structure, d is a groove spacing of the blazed grating structure, \u03b8 is a blazing angle of the blazed grating structure, k is an interference level, \u03bb is a blazed wavelength, and an angle between diffracted light of the blazed grating structure and the macro plane normal of the blazed grating structure is \u03b2=2\u03b8\u2212\u03b1.
