A plasma flat lamp includes an upper plate (10), a lower plate (20) separated a predetermined distance from the upper plate, a wall portion (70) for forming a sealed discharge space between the upper and lower plates (10,20), a discharge gas (80) filled in the discharge space, a first pair of electrodes including a first upper plate electrode (31) and a first lower plate electrode (32) arranged to face each other on each of the upper and lower plates (10,20) with the discharge space interposed therebetween, and a second pair of electrodes including a second upper plate electrode (41) separated a predetermined distance from the first upper plate electrode and a second lower plate electrode (42) separated a predetermined distance from the first lower plate electrode arranged to face each other on each of the upper and lower plates with the discharge space interposed therebetween. Thus, the plasma flat lamp according to the present invention has a stable discharge feature which is a merit of the conventional electrodes discharge flat lamp and a high luminance of light emission which is a feature of the facing surfaces discharging type, while not having a low luminance and unstable discharge feature of the conventional surface discharge type flat lamp and facing electrodes discharging flat lamp, respectively.
