What is claimed is: 1. A backlight assembly comprising: a light source generating light; and a light-guide plate guiding the light, the light-guide plate including: a light incident surface receiving the light from the light source, the light incident surface having a plurality of protruding portions and at least one recessed portion between the protruding portions, the light source being disposed adjacent to the recessed portion; an upper surface emitting the received light from the light source; and a lower surface fading the upper surface. 2. The backlight assembly of claim 1, wherein a top and bottom of the recessed portion are open. 3. The backlight assembly of claim 1, wherein the light incident surface of the light-guide includes a plurality of recessed portions, and the light source includes a plurality of light emitting diodes disposed on each of the recessed portions. 4. The backlight assembly of claim 3, further comprising a printed circuit board providing the light source with a driving signal to drive the light source, wherein the light source part is electrically connected to the printed circuit board. 5. The backlight assembly of claim 4, wherein a light-diffusing pattern is formed on the recessed portion to diffuse the incident light. 6. The backlight assembly of claim 5, further comprising a receiving container receiving the light source and the light-guide plate, wherein the receiving container is in contact with the protruding portions. 7. A liquid crystal display device comprising: an liquid crystal display panel displaying an image; a light source providing the liquid crystal display panel with light; and a light-guide plate guiding the light, the light-guide plate including: a light incident surface receiving the light from the light source, the light incident surface having a plurality of protruding portions and at least one recessed portion between the protruding portions, the light source being disposed adjacent to the recessed portion; an upper surface emitting the received light from the light source; and a lower surface facing the upper surface. 8. The liquid crystal display device of claim 7, wherein a top and bottom of the recessed portion of the light incident surface are open. 9. The liquid crystal display device of claim 7, wherein a light-diffusing pattern is formed on the recessed portion to diffuse the incident light. 10. The liquid crystal display device of claim 7, wherein the light incident surface of the light-guide plate includes a plurality of recessed portions, and the light source includes a plurality of light emitting diodes disposed on each of the recessed portions. 11. The liquid crystal display device of claim 10, further comprising a printed circuit board providing the light source with a driving signal to drive the light source, wherein the light source is electrically connected to the printed circuit board. 12. The liquid crystal display device of claim 11, wherein the printed circuit board is disposed at an end portion of the light-guide plate. 13. The liquid crystal display device of claim 10, further comprising a first receiving container receiving the light source and the light-guide plate, wherein the first receiving container is in contact with the protruding portions. 14. The liquid crystal display device of claim 13, wherein the light-guide plate further includes a fixing member, and the first receiving container further includes a fixing groove for receiving the fixing member. 15. The liquid crystal display device of claim 13, further comprising a second receiving container combined with the first receiving container, and a reflecting plate disposed between the light-guide plate and the second receiving container. 16. The liquid crystal display device of claim 15, further comprising a top chassis combined with the second receiving container to cover an edge portion of the liquid crystal display panel.
