EXTERNAL ELECTRODE DRIVEN DISCHARGE LAMP, METHOD FOR PRODUCING SAME, AND LIQUID CRYSTAL DISPLAY

摘要

Disclosed is an external electrode driven discharge lamp comprising a hollow glass bulb (1) forming a hermetically sealed space, a discharge gas sealed in the glass bulb, and an external electrode (22) arranged outside the glass bulb. The external electrode is a plate composed of a conductive material, and is connected to the glass bulb with a fusion-bonding layer (5) whichi is composed of a solder alloy. The solder alloy is an alloy of bismuth and tin containing 30-70% by weight of bismuth. Since the linear expansion coefficient of the glass bulb is almost equal to the linear expansion coefficient of the solder alloy, damages to the glass bulb caused by thermal impact during production can be suppressed.
