    Abstract: Provided are a backlight and a liquid crystal display device including the same. The backlight unit includes a light source assembly which emits light; a light guide plate which receives at a light incident surface thereof light from the light source assembly; and a bottom chassis having a bottom unit on which the light guide plate is disposed. The bottom unit of the bottom chassis has a first bottom portion which is arranged in the vicinity of the light incident surface and has a first recess, a second bottom portion which is bent diagonally to the cross sectional surface and has a second recess, and a third bottom portion which is bent at the second bottom portion in the direction parallel to the first bottom portion and disposed higher than the first bottom portion. A light absorbing member is disposed in the first and second recesses.

    Abstract: The high intensity light output of edge lighting point light sources such as LEDs may generate undesired leakage light that is optically conducted by way of a continuum of the material of a components affixing adhesive member. In accordance with present disclosure, air filled grooves or other such discontinuities are formed in the adhesive member along respective light output pathways of the respective point light sources. One corresponding embodiment comprises spaced apart LEDs mounted on an FPCB; a light guide plate (LGP) disposed adjacent to the LEDs; a main support accommodating the LEDs and the LGP; and an adhesive member formed to affix together the FPCB, the main support, and the light guide, wherein the adhesive member is patterned to define air filled grooves along respective light output pathways of the LEDs.
