Patent ID: 7473018

Claim:
A back light assembly, comprising: a light guide plate including a light incidence face, a light reflecting face and a light exiting face, the light reflecting face reflecting a first light toward the light exiting face to transform the first light into a second light, the second light exiting from the light exiting face, a width of the light incidence face being a first distance; a light reflecting member for covering the light incidence face so as to form a lamp receiving space, the lamp receiving space being defined by the light reflecting member and the light incidence face; at least two lamps disposed in the lamp receiving space, the two lamps being spaced apart from each other by a second distance, a sum of diameters of the two lamps and the second distance being longer than the first distance; and a receiving container for receiving the light guide plate and the light reflecting member, wherein the light reflecting member includes a chamfer disposed at an edge where a virtual line passing through centers of the two lamps meets the light reflecting member, whereby the chamfer reflects the light generated by the lamps toward the light incident face.
