Abstract: A backlight module includes a plurality of first light emitting elements and a light guiding plate including a first side, a second side and a light output side having microstructures at least disposed in a near-light region of the light guiding plate. The near-light region is defined as from a first line to a predetermined second line at the light output side. The microstructure has a width P and height H, the light-guiding plate has a thickness T, a pitch between the adjacent first light-emitting elements is defined as PLED, a projection distance from a luminance measuring line of the backlight module to the first light-emitting elements is defined as A. Under the conditions 0
