    • A back-light module including a light guide plate (LGP), first light-emitting devices, and second light-emitting devices is provided. The LGP has a top-emitting surface, a bottom surface and a side surface. The LGP has at least one indentation. The indentation has a first light-incident sidewall and a pair of second light-incident sidewalls. The second light-incident sidewalls are located on two sides of the first light-incident sidewall and adjacent to the first light-incident sidewall. Normal vectors of the second light-incident sidewalls and the first light-incident sidewall are not parallel. The first light-emitting devices are located in the indentation, and a first light beam propagating toward the first light-incident sidewall is emitted from each of the first light-emitting devices. The second light-emitting devices are located in the indentation, and a second light beam propagating toward one of the second light-incident sidewalls is emitted from each of the second light-emitting devices.
    • 提供了包括导光板(LGP),第一发光器件和第二发光器件的背光模块。 LGP具有顶部发射表面,底表面和侧表面。 LGP至少有一个缩进。 凹陷具有第一光入射侧壁和一对第二光入射侧壁。 第二光入射侧壁位于第一光入射侧壁的两侧并与第一光入射侧壁相邻。 第二光入射侧壁和第一光入射侧壁的法线矢量不平行。 第一发光装置位于凹陷中,并且朝向第一入光侧壁传播的第一光束从每个第一发光装置发射。 第二发光器件位于压痕中,并且从第二发光器件的每一个发射朝向第二光入射侧壁中的一个传播的第二光束。
