Flat lamp

摘要

A flat lamp comprises an upper substrate (120), a lower substrate (100), first electrode portions (111), and second electrode portions (112). The lower and upper substrates (100,120) are arranged to face each other with a certain distance therebetween and form at least one discharge cell (130) between the upper and lower substrates (120,100). A pair of first and second electrode portions (111,112) is formed in each of the discharge cells (130) on at least one of the upper and lower substrates (120,100). Each of the first and second electrode portions (111,112) includes a plurality of electrodes.
