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.
