Abstract: A backlight unit includes a light conversion member; a light guide plate including a light exit surface, a rear surface facing the light exiting surface, and connection surfaces including a first surface and a second surface facing each other to connect the light exit surface and the rear surface; a reflective member; and a light source emitting a first color light incident to the first surface and a portion of the first color light reaches the second surface on which the reflective member is disposed to specularly reflect the portion of the first color light. The light conversion member is disposed on the light exit surface, receives the first color light from the light guide plate, and emits a second color light different from the first color light.

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.
