ABSTRACT:
The discharge space of a flat type fluorescent lamp in which a pair of electrodes are oppositely positioned for producing discharge therebetween establishes a predetermined elongated width W along the pair of electrodes and a prescribed height H in a direction perpendicular to the discharge direction. A fill including argon is sealed in the discharge space at a target pressure F (torr) which satisfies the following relationship when an aspect ratio F defined by the ratio of the predetermined elongated width W to the prescribed height H is equal to or greater than four and is equal to or less than eight: 10.ltoreq.P.ltoreq.-5/2 (F-4)+40; and the following relationship when the aspect ratio F is equal to or greater than eight and is equal to or less than eighteen: 10.ltoreq.P.ltoreq.30.
