A cold cathode fluorescent lamp (CCFL) is disclosed that provides a structure which may be driven in parallel. For this purpose, a lamp drive device comprises a plurality of CCFLs connected in parallel, a first current limiting unit connected to the plurality of CCFLs to control the magnitude of supplied power so as to discharge the CCFLs, and an inverter for changing the magnitude of supplied AC power and supplying the changed AC power to the first current limiting unit. This parallel drive CCFL structure may reduce manufacture costs of CCFL and minimize device failure rates. |
