Beschreibung
Zusammenfassung:	A backlight module includes a light guide plate having an upper surface, a lower surface, and light-adjusting structures on the lower surface; an optical sheet disposed opposite to the upper surface of the light guide plate; and a light source disposed adjacent to the light guide plate, wherein a light emitted by the light source has a first brightness distribution in a first direction after passing through the light guide plate, and the first brightness distribution has a first maximum brightness corresponding to a first angle and a second maximum brightness corresponding to a second angle, and an absolute value of the first angle and an absolute value of the second angle are greater than 60 degrees, respectively, wherein an absolute value of a difference between the first maximum brightness and the second maximum brightness is less than or equal to 30% of the first maximum brightness.
