Liquid crystal display device
View Patent ↗Provided is a liquid crystal display device that offers improved heat dissipation and that can prevent a light source from being damaged when such liquid crystal display device is vibrated or dropped. The liquid crystal display device is provided with a liquid crystal cell 2 , illuminating means 3 that is located behind the liquid crystal cell 2 , and a frame body 4 that supports the liquid crystal cell 2 and the illuminating means 3 . The illuminating means 3 includes a light guide plate 9 , light sources 13 and 14 that are located so as to face one side face of the light guide plate 9 , and a holder 12 that supports the light sources 13 and 14 . There is provided a reinforcing member 15 between the light guide plate 9 and the holder 12 , and there is provided a shock-absorbing member 16 located on a side face of the reinforcing member 15 and that makes contact with or lies adjacent to the one side face of the light guide plate 9.
1. A liquid crystal display device comprising:
a liquid crystal cell;
illuminating means that is located behind the liquid crystal cell; and
a frame body that supports the liquid crystal cell and the illuminating means, wherein
the illuminating means includes
a light guide plate,
a light source that is located so as to face one side face of the light guide plate, and
a holder that supports the light source,
there is provided a reinforcing member between the light guide plate and the holder,
there is provided a shock-absorbing member located on a side face of the reinforcing member and that makes contact with or lies adjacent to the one side face of the light guide plate,
the reinforcing member is so formed, as seen in cross-section, as to cover the holder from three directions,
there is provided a reflector that covers the light source and that is open toward the light guide plate, and
the reflector has a notch portion in a position where the reflector faces the reinforcing member.
2. The liquid crystal display device of claim 1 , wherein the shock-absorbing member is fixed to the reinforcing member.
3. The liquid crystal display device of claim 1 , further comprising;
a reflector that covers the light source and that is open toward the light guide plate, wherein
the frame body has formed therein a projection that covers the reflector, and
there is provided a first adhesive member that is bonded to the reflector and to the projection.
4. The liquid crystal display device of claim 1 , wherein
the frame body is formed as a picture frame-shaped member having a mounting portion around an opening,
the liquid crystal display device further comprises
a radiator plate located on the mounting portion, and
a reflecting plate located on the radiator plate, and
the light guide plate is located on the reflecting plate, and
the radiator plate is exposed through the opening.
5. The liquid crystal display device of claim 4 , wherein
there is provided a second adhesive member bonded to a back face of the light guide plate near another side face of the light guide plate facing away from the one side face thereof facing the light source and to a front face of the radiator plate.
6. The liquid crystal display device of claim 1 , wherein
the frame body has a first supporting member that supports the liquid crystal cell, and
the shock-absorbing member is formed integrally with the first supporting member.
7. A liquid crystal display device comprising:
a liquid crystal cell;
illuminating means that is located behind the liquid crystal cell; and
a frame body that supports the liquid crystal cell and the illuminating means, wherein
the illuminating means includes
a light guide plate,
a light source that is located so as to face one side face of the light guide plate, and
a holder that supports the light source,
there is provided a reinforcing member between the light guide plate and the holder,
there is provided a shock-absorbing member located on a side face of the reinforcing member and that makes contact with or lies adjacent to the one side face of the light guide plate,
the frame body has a first supporting member that supports the liquid crystal cell, and
the shock-absorbing member is formed integrally with the first supporting member.
