Juxtaposed discharge tubes with opposed trigger electrodes

摘要

A light emitting device wherein one of a plurality of juxtaposed discharge tubes which is to remain not emitting light is prevented from being caused to emit light by induction by an adjacent one of the discharge tubes which is to emit light, thereby enabling fully independent control of light emission by the discharge tubes. In the light emitting device, trigger electrodes of each adjacent ones of a plurality of juxtaposed discharge tubes are located at opposite positions to each other with respect to the adjacent discharge tubes.
