Patent ID: 8643806

Claim:
A liquid crystal display device comprising: a liquid crystal display panel; a top chassis arranged on a front surface of the liquid crystal display panel; a bottom chassis disposed behind a rear surface of the liquid crystal display panel; at least one optical sheet arranged between the liquid crystal display panel and the bottom chassis; a light-guide portion arranged between the bottom chassis and the optical sheet, the light-guide portion comprising a light-emitting surface facing the liquid crystal display panel and an incident surface perpendicular to the light-emitting surface; a reflective portion arranged between the light-guide portion and the bottom chassis; a side frame comprising a side wall to surround an outside of the light-guide portion, an outside of the reflective portion and an outside of the bottom chassis, and a support rib extending from the side wall to mount the liquid crystal display panel and the optical sheet; a printed circuit board arranged between the side frame and the bottom chassis, the printed circuit board comprising a plurality of light-emitting diodes each having a light-emitting surface; a reflective surface arranged in an inner surface of the side frame, the reflective surface directing light from the plurality of light-emitting diodes to the incident surface; a holder to support one surface of the printed circuit board and connect the side frame with the bottom chassis; and a light-shielding member disposed above the light-emitting surfaces of the light-emitting diodes, configured to prevent light irradiated from the light-emitting surfaces of the plurality of light-emitting diodes from being incident to a lower edge of the incident surface, wherein the light-shielding member is an extending portion protruding outward from an edge of the reflective portion so that the light-shielding member extends from a side surface of the light-guide portion.
