Abstract
The present invention provides a backlight device that has a heat-generating light source, such as a fluorescent tube. This backlight device includes; fluorescent tubes that emit light when power is supplied to the fluorescent tube electrodes; and a light guide plate that guides the light emitted from the fluorescent tubes to a liquid crystal panel. In this backlight device, heat release members for releasing the heat from the fluorescent tube electrodes are provided at the corners of the light guide plate that face the fluorescent tube electrodes of the fluorescent tubes. With these heat release members, the light guide plate is prevented from melting.
Claims7
A backlight device comprising:
- a light source that emits light when power is supplied to electrodes thereof;
- a light guide plate for guiding the light emitted from the light source to a liquid crystal panel;
- and
- heat release members for releasing heat generated by the electrodes, the heat release members being located at least either by the sides of the electrodes of the light source or at the corners of the light guide plate facing the electrodes.
A liquid crystal display comprising:
- a liquid crystal panel;
- a backlight device that includes:
- a light source that emits light when power is supplied to electrodes thereof;
- a light guide plate for guiding the light emitted from the light source to the liquid crystal panel;
- and heat release members for releasing heat generated by the electrodes, the heat release members being located at least either by the sides of the electrodes of the light source or at the corners of the light guide plate corresponding to the electrodes;
- and
- a light guide plate that is provided at the light-entering side of the backlight device, and guides the light emitted from the backlight device to the liquid crystal panel.
