Liquid crystal display device
View Patent ↗A liquid crystal display device ( 1 ), comprising a liquid crystal display panel and an illumination unit ( 10 ). The illumination unit ( 10 ) further comprises a housing ( 11 ) having a rectangular bottom wall face and having, at its side peripheral edge parts, cut and erected pieces ( 14 1 ) and ( 14 2 ) formed by cutting out a part of the bottom wall surface and projecting the cutout parts to the rear surface, and a frame-shaped intermediate frame ( 20 ) having a display window ( 20 0 ) at its center part to which an illuminating member stored in the housing ( 11 ) is fixed. The intermediate frame ( 20 ) comprises locking pieces ( 23 1 ) inserted into opening parts ( 14 0 ) formed, when the cut and erected pieces are cut and raised, at positions corresponding to the cut and erected pieces ( 14 1 ) and ( 14 2 ). When the intermediate frame ( 20 ) is fixed to the housing ( 11 ), clearances formed between the cut and erected pieces ( 14 1 ) and ( 14 2 ) and the locking pieces ( 23 1 ) form a lead fixing parts for holding fixing leads ( 4 ) extracted from the illuminating member. The liquid display device thus provided can easily fix the leads extracted from the housing.
1. A liquid crystal display device comprising
a liquid crystal display panel and
an illumination unit that irradiates said liquid crystal display panel,
said illumination unit including
a housing having a rectangular bottom wall surface and cut and erected pieces formed at its side peripheral edge part by cutting out a part of said bottom wall surface and projecting the cut-out part from a rear surface,
an illuminating member contained in said housing, and
an intermediate frame that fixes said illuminating member and has at its central part a display window;
said intermediate frame having, at positions corresponding to said cut and erected pieces, locking pieces that are to be inserted into openings that result when cutting out and erecting said cut and erected pieces; and clearances that are formed, when said intermediate frame has been fixed to said housing, between said cut and erected pieces of said housing and said locking pieces of said intermediate frame forming a lead fixing part for holding and fixing leads extracted from said illuminating member.
2. The liquid crystal display device according to claim 1 , wherein said lead fixing part is provided on the side peripheral edge part at a position close to a position where said leads are extracted from said illumination unit.
3. The liquid crystal display device according to claim 1 , wherein said housing is formed of a sheet metal and said intermediate frame is formed of a synthetic resin material.
4. The liquid crystal display device according to claim 1 , wherein said lead fixing part is provided on the side peripheral edge part at a position close to a position where said leads are extracted from said illumination unit, and said housing is formed of a sheet metal and said intermediate frame is formed of a synthetic resin material.
5. The liquid crystal display device according to claim 1 , wherein each of said intermediate frame and said housing includes locking means to be joined together.
6. The liquid crystal display device according to claim 1 , wherein said lead fixing part is provided on the side peripheral edge part at a position close to a position where said leads are extracted from said illumination unit, and each of said intermediate frame and said housing includes locking means to be joined together.
7. The liquid crystal display device according to claim 1 , wherein said housing is formed of a sheet metal and said intermediate frame is formed of a synthetic resin material, and each of said intermediate frame and said housing includes locking means to be joined together.
8.
