Abstract: A backlight module includes a light guiding unit having a light input surface and a light-emitting unit having light-emitting elements disposed along a first direction and adjacent to the light input surface. A second direction is from the light input surface to the light-emitting unit. A first protruding portion of the light guiding unit includes a sharp protrusion tip at the bottom surface and a part of the light input surface. A curved convex connecting surface of the light input surface connects to the first protruding portion to form a turning portion which is disposed between the connecting surface and the first protruding portion, and is at its intermediate portion and outwardly protrudes toward the light-emitting elements along the second direction. The light-emitting elements are across from the connecting surface and generally positioned above the first protruding portion in the third direction.

Abstract: 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.
