Disclosed is a flat panel display that can prevent image quality degradation by preventing the current transmitted to the organic light emitting diode or liquid crystal of the flat panel display from being changed by the leakage current and keeping the current stably. The flat panel display comprises: a first switching element whose control electrode is electrically coupled to a scan line, being electrically coupled between a data line and a first voltage line; a second switching element whose control electrode is electrically coupled to the scan line, being electrically coupled between the first switching element and first voltage line; a capacitive element whose first electrode is electrically coupled between the first and second switching elements; a drive transistor whose control electrode is electrically coupled to the second switching element, being electrically coupled between the first voltage line and a second voltage line; and an organic light emitting diode electrically coupled between the drive transistor and second voltage line. |
