PROBLEM TO BE SOLVED: To improve edge dark zone phenomenon in an electrode structure applied for a plane fluorescent lamp of a back light of a liquid crystal display in this invention. SOLUTION: This electrode structure is provided with a first auxiliary electrode and a second auxiliary electrode, a first edge electrode and a second edge electrode located between the first auxiliary electrode and the second auxiliary electrode, respectively coupled with the first auxiliary electrode and the second auxiliary electrode and having the same polarity, and at least one electrode located between the first edge electrode and the second edge electrode. In the electrode structure, interaction between the first edge electrode or the second edge electrode and an adjacent electrode is strengthened respectively by the first auxiliary electrode and the second auxiliary electrode or the width of the edge electrodes is increased by 1.5 to 4 times of the width of an original electrode for improving current density of the edge electrodes and the luminance of an edge discharge section so that big difference does not occur between the luminance of the central area and the luminance of the edge zone.
