Abstract
A flat lamp with horizontal facing electrodes is provided, in which a front substrate and a rear substrate are spaced such as to face each other. Walls between the front and rear substrates form a discharging space filled with a discharge gas. A plurality of front electrodes and a plurality of rear electrodes are provided on facing surfaces of the front and rear substrates, respectively. The front and rear electrodes, formed in strips, are arranged in such a way that the front electrodes alternate with the rear electrodes. Accordingly, the discharging distance between front and rear electrodes is lengthened, and many fine discharging operations occur between tip electrodes extending from the lateral sides of the electrode strips and flat portions of corresponding electrode strips. Therefore, a current concentration is prevented, thereby achieving uniform discharging. Also, brightness of the flat lamp increases.
