LIGHTING DEVICE, BACK LIGHT UNIT, AND LIQUID CRYSTAL DISPLAY DEVICE

摘要

Provided is a lighting device comprising a lighting circuit for lighting a plurality of hot-cathode lamps having filaments at two ends, preheating circuits for preheating the individual filaments of the hot-cathode lamps, at least one first circuit substrate arranged near one filament of the hot-cathode lamps, and at least one second circuit substrate arranged near the other filament of the hot-cathode lamps. The lighting circuit is packaged in either the first circuit substrate or the second circuit substrate, and the preheating circuits are so divided as are packaged or wired in the first circuit substrate and the second circuit substrate.
