Abstract
The present invention relates to a light source device including discharge tubes that emit light by discharging in a thin atmosphere, a method of producing the light source device, and a display apparatus in which the light source device is employed. This light source device includes discharge tubes and a heat conductive member that is brought into contact with the neighboring area of the electrodes of the discharge tubes so as to locally cool down the neighboring area of the electrodes. In the light source device, a low heat conductivity member having lower heat conductivity than the heat conductive member is interposed between the heat conductive member and the discharge tubes. With such a structure, the luminance in the entire light source device can be increased and made uniform, and the reliability of the light source device can be increased accordingly.
