A light guide plate (12), a manufacturing method for the light guide plate (12) and a backlight module (10) containing the light guide plate (12). The light guide plate (12) is fixed in a back panel (11) with a plurality of fixing pieces (110). The light guide plate (12) comprises an in-light surface (122), a reflection surface connected to the in-light surface (122), and an out-light surface (124) which is opposite to the reflection surface and is connected to the in-light surface (122), wherein the out-light surface (124) comprises an out-light body (1240), and a plurality of positioning pieces (1242) arranged on the out-light body (1240) and corresponding to the plurality of fixing pieces (110). The plurality of positioning pieces (1242) cooperate with corresponding fixing pieces (110) so that the light guide plate (12) is fixed in the back panel (11). A blank region (1244) is provided at the cooperation position between each positioning piece (1242) on the out-light body (1240) and a corresponding fixing piece (110), and optical microstructures (1246) are provided in the regions outside the plurality of blank regions (1244) of the out-light body (1240). |
