PURPOSE:To eliminate mounting of an exhaust pipe and make production easy by sealing flat plates on both sides of the side wall of a hollow pipe to form a flat discharge container, and accommodating a plurality of electrodes and phosphor layers to obtain a flat light source. CONSTITUTION:A hollow pipe 24 comprising a glass tube having a diameter of 1-10mm is bent to form a side wall 25, and flat plates 22, 23 are bonded on its both sides with, for example, glass frit to form a discharge container 21. A hole 26 which connects the side wall 25 and the inside of the discharge container 21, and a hole 27 which connects the side wall 25 and the outside are formed. Rare gas and mercury are sealed and a plurality of electrodes and phosphor layers are accommodated in the container 21 to form a flat light source used for a transmission type liquid crystal display. Since this light source is exhausted through the side wall, mounting of exhaust pipe is eliminated. Therefore, the production is made easy. |
