    摘要: A discharge lamp device (L) which drives a discharge tube (3) filled with a rare gas and has a first electrode mounted at the inside of the tube and a second electrode mounted at the outside of the tube, includes a driving circuit (5) that applies a voltage between the first and second electrodes (1, 2a-2c). The driving circuit (5) applies a positive rectangular wave voltage to the first electrode (1) with a potential of the second electrode (2a-2c) being a reference potential (0V). A backlight (B) includes at least one discharge tube (3) and the discharge lamp device (L).

    摘要: A light source device includes at least one discharge tube (20), a discharge medium sealed inside the discharge tube (20), and first and second electrodes (21 and 22) for exciting the discharge medium. The first electrode (21) is arranged inside or outside the discharge tube (20), and the second electrode (22) has a plurality of contact portions at which the second electrode (22) is in contact with an outer surface of the discharge tube (20). The contact portions are located at different distances from the first electrode (21) and are provided discontinuously. Xenon gas and at least one selected from argon gas and krypton gas are sealed in the discharge tube (20), in which the xenon gas accounts for 60vol% to 80vol%. 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 (100) includes a discharge tube (20), a discharge medium sealed inside the discharge tube (20), and inner and outer electrodes (21) and (22) for exciting the discharge medium. The outer electrodes (22) include a first outer electrode (23) and a second outer electrode (24) that are connected electrically with each other. The first outer electrode (23) is in contact with an outer surface of the discharge tube (20) at a plurality of first contact portions that are located at different distances from the inner electrode (21) and are provided discontinuously. The second outer electrode (24) is in contact with the outer surface of the discharge tube (20) at second contact portions. The second contact portions are arranged closer to the inner electrode (21) 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.
