Abstract

A liquid crystal display device includes a liquid crystal display panel and a backlight including a light source for irradiating the liquid crystal display panel, in which the backlight includes at least a plurality of linear fluorescent lamps arranged in parallel in a plane facing the liquid crystal display panel, fluorescent lamp supporting bases supporting the linear fluorescent lamps, and a frame to which the fluorescent lamp supporting bases are fixed, the fluorescent lamp supporting bases each include a fluorescent lamp supporting member directly supporting the linear fluorescent lamp and a fixing portion fixed to the frame, and a recess is formed in the frame at a portion just behind the fluorescent lamp supporting member.

Claims (16)

1. A liquid crystal display device comprising:

a liquid crystal display panel; and

a backlight including a light source for irradiating the liquid crystal display panel, wherein

the backlight includes at least a plurality of linear fluorescent lamps arranged in parallel in a plane facing the liquid crystal display panel, fluorescent lamp supporting bases supporting the linear fluorescent lamps, and a frame to which the fluorescent lamp supporting bases are fixed,

the fluorescent lamp supporting bases each include a fluorescent lamp supporting member holding the linear fluorescent lamp and a fixing portion for fixing the fluorescent lamp supporting base to the frame, and

a recess is formed in the frame at a position where the fluorescent lamp supporting member is provided,

wherein the recess in the frame is formed at portions just behind the fluorescent lamp supporting member and the recess has a bottom surface spaced from a bottom surface of the fluorescent lamp supporting base.

2. A liquid crystal display device according to claim 1 , wherein a depth of the recess is set at least equal to a height of the fluorescent lamp supporting base.

3. A liquid crystal display device according to claim 1 , wherein the fixing portion of the fluorescent lamp supporting base includes an engaging portion inserted into the frame, and the engaging portion is formed at a position not overlapped with the fluorescent lamp supporting member.

4. A liquid crystal display device comprising:

a liquid crystal display panel; and

a backlight including a light source for irradiating the liquid crystal display panel, wherein

the backlight includes at least a plurality of linear fluorescent lamps arranged in parallel in a plane facing the liquid crystal display panel, fluorescent lamp supporting bases supporting the linear fluorescent lamps, and a frame to which the fluorescent lamp supporting bases are fixed,

the fluorescent lamp supporting bases each include a fluorescent lamp supporting member holding the linear fluorescent lamp and a fixing portion for fixing the fluorescent lamp supporting base to the frame, and

a recess is formed in the frame at a position where the fluorescent lamp supporting member is provided,

wherein the fixing portion of the fluorescent lamp supporting base includes an engaging portion inserted into the frame, and the engaging portion is formed at a position not overlapped with the fluorescent lamp supporting member.
