Light source device and liquid crystal display employing the same |
摘要 |
A light source device includes at least one discharge tube, a discharge medium sealed inside the discharge tube, and first and second electrodes for exciting the discharge medium. The first electrode is arranged inside or outside the discharge tube, and the second electrode has a plurality of contact portions at which the second electrode is in contact with an outer surface of the discharge tube. The contact portions are located at different distances from the first electrode and are provided discontinuously. Thus, it is possible to provide a light source device with an improved light emission efficiency, and a liquid crystal display device in which the light source device is employed.
