摘要： A light source device includes a discharge tube, a discharge medium sealed inside the discharge tube, and inner and outer electrodes for exciting the discharge medium. The inner electrode is arranged inside the discharge tube. The outer electrode includes a first outer electrode and a second outer electrode that are connected electrically with each other. The first outer electrode is in contact with an outer surface of the discharge tube at a plurality of first contact portions that are located at different distances from the inner electrode and are provided discontinuously. The second outer electrode is in contact with the outer surface of the discharge tube at second contact portions. The second contact portions are arranged closer to the inner electrode than the first contact portions at a surface density greater than that of the first contact portions. Thus, it is possible to provide a light source device with decreased fluctuations in the brightness distribution and with higher brightness, and a liquid crystal display device in which the light source device is employed.

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. Xenon gas and at least one selected from argon gas and krypton gas are sealed in the discharge tube, in which the xenon gas accounts for 60 vol % to 80 vol %. Thus, it is possible to provide a light source device and a liquid crystal display device that provide light emission with high brightness and excellent brightness distribution and that can be manufactured readily.

摘要： A light source device includes a substrate, a plurality of discharge tubes arranged on one principal surface of the substrate, a driving circuit mounted on the other principal surface of the substrate that is opposite to the foregoing principal surface, a discharge medium sealed in the discharge tubes, and first and second electrodes for exciting the discharge medium. The foregoing discharge medium does not contain mercury. Thus, the light source device can be formed smaller in size and thinner in thickness, and a liquid crystal display device employing the same can be provided.
