Liquid crystal display
View Patent ↗An object of the invention is to provide a liquid crystal display of which a reduction in thickness can be realized without increasing the thickness of a frame member configuring a backlight. Also, another object is to provide a liquid crystal display which secures a sufficient property of insulation from electrode fittings and lamp cables. A liquid crystal display includes a liquid crystal display panel, and a backlight disposed at the back of the liquid crystal display panel, wherein the backlight includes a frame member DFR which is of a rectangular box shape, a plurality of fluorescent lamps FL, disposed inside the frame member, each of which includes an electrode at either end, a first lamp cable CB 1 for supplying lighting power to one of the electrodes of each fluorescent lamp, a second lamp cable CB 2 for supplying lighting power to the other electrode of each fluorescent lamp, and a cable guide CG which, being disposed along an inside long-side edge of the frame member, holds the first and second lamp cables, wherein the cable guide includes a first opening through which the first and second lamp cables are led out, and wherein the frame member includes a second opening through which the first and second lamp cables led out from the cable guide are led out to the exterior of the frame member.
1. A liquid crystal display comprising:
a liquid crystal display panel; and
a backlight disposed at the back of the liquid crystal display panel, wherein
the backlight includes a frame member which is of a rectangular box shape, a plurality of fluorescent lamps, disposed inside the frame member, each of which includes an electrode at either end, a first lamp cable for supplying lighting power to one of the electrodes of each fluorescent lamp, a second lamp cable for supplying lighting power to the other electrode of each fluorescent lamp, and a cable guide which, being disposed along an inside long-side edge of the frame member, holds the first and second lamp cables, wherein
the cable guide includes a first opening through which the first and second lamp cables are led out, and wherein
the frame member includes a second opening through which the first and second lamp cables led out from the cable guide are led out to the exterior of the frame member.
2. The liquid crystal display according to claim 1 , wherein
the cable guide is fixed to a sidewall of the frame member by snap fittings provided on the cable guide.
3. The liquid crystal display according to claim 1 , further comprising:
electrode fittings which support the plurality of electrodes of the fluorescent lamps, and supply power to the fluorescent lamps; and side molds which support the electrode fittings, are disposed along inside short-side edges of the frame member, wherein
the cable guide and side molds have overlapping portions.
4. The liquid crystal display according to claim 3 , wherein
projections extended parallel to the short sides of the frame member are formed on each of the side molds.
5. The liquid crystal display according to claim 1 , wherein
a reflecting sheet is provided between the fluorescent lamps and the frame member, wherein
a gap is provided along the long-side edge of the frame member, between the reflecting sheet and the frame member, and the cable guide is disposed in the gap.
6. The liquid crystal display according to claim 5 , wherein
the reflecting sheet includes an inclined portion along the long-side edge of the frame member, and the cable guide includes an abutment portion which is a surface extending along the inclined portion of the reflecting sheet.
7. The liquid crystal display according to claim 6 , wherein
the cable guide includes a groove which opens to the abutment portion, is for containing the lamp cables.
8. The liquid crystal display according to claim 5 , wherein
the cable guides are disposed on both long-side edges of the frame member.
