Abstract

In a backlight assembly and a display apparatus having the backlight assembly, the backlight assembly includes a light source, a light guide, a first reflector, and an optical unit. The light guide is disposed adjacent to the light source, extends substantially parallel with a longitudinal direction of the light source, and refracts light emitted from the light source. The first reflector is disposed under the light guide and reflects the refracted light toward the optical unit. The optical unit is disposed over the first reflector such that an empty space is formed between the optical unit and the first reflector.

Description

Technical field [0001] Exemplary embodiments of the present invention relate to a backlight assembly and a display device having the backlight assembly. Background technique [0002] Generally, the display device includes a backlight assembly and a display panel. The backlight assembly emits light, and the display panel uses the light from the backlight assembly to display images. The light source may be provided at a side portion of the backlight assembly (referred to as an edge-light type backlight assembly) to reduce the thickness of the display device. [0003] The edge-light type backlight assembly includes a light guide plate and a reflective plate. The light guide plate guides light from a light source provided at the side of the light guide plate. The reflective plate is disposed under the light guide plate and reflects light to the display panel. Recently, the structure of a newly developed display device does not include a light guide plate to reduce the weight of the...
