In a cell drive-type flat display panel, a metal electrode pad (26) and common signal line (24) are disposed outside the area (effective area) facing a recessed portion forming a cell. The individual cell electrode (20) acting as a cell electrode within the effective area is connected to a metal electrode pad (26) by extending each cell electrode to the metal electrode pad (26), while the metal electrode is not extended toward the effective area to cover each cell electrode. A common electrode (22) is connected to the common signal line (24) by extending each cell electrode to the metal electrode pad (26), while the metal electrode is not extended toward the effective area and to cover each cell electrode. This structure makes the cell electrodes flat and can reduce the drive voltage from the effect resulting from the suppressed dielectric film. The metal electrode pad (26) has a top surface on which a pin electrode is posted. The dielectric layer has an opening from which the metal electrode pad (26) is exposed, and covers the edges of the metal electrode pad (26). This structure can prevent the transparent electrode layer bridging the individual electrode (20) with the metal electrode pad (26) from making contact with the dielectric layer or frit with high reactivity.
