A reflector is incorporated in a liquid crystal display panel for directing light to an optical path from a lamp to a liquid crystal panel, and a high voltage line is directly connected to an electrode of the lamp, but a low voltage line is connected through a conductive pattern formed on the reflector to the other electrode of the lamp, wherein the conductive pattern is formed from a layer of conductive filler printed on the reflector through thermosetting so that the conductive pattern is thick enough to withstand thermal stress without enlargement of the liquid crystal display unit.
