Patent ID: 7473021

Claim:
A liquid crystal display comprising: a liquid crystal display panel for modulating light to form an image; and a back light unit having a plurality of lamp tubes without inside electrodes and which are discharged by outside electrodes disposed along an outer surface of said plurality of lamp tubes, said back light unit being disposed behind said liquid crystal display panel; wherein each of said plurality of lamp tubes has a first outside electrode which is one of said outside electrodes disposed at one end portion thereof and a second outside electrode which is one of said outside electrodes at another end portion thereof; wherein one conductive member directly electrically connects said first outside electrode which is disposed at one of said plurality of lamp tubes with said first outside electrode disposed at an adjacent another of said plurality of lamp tubes; wherein a second conductive member which is separate from said one conductive member directly electrically connects said second outside electrode which is disposed at said one of said plurality of lamp tubes with said second outside electrode disposed at said adjacent another of said plurality of lamp tubes; wherein said one conductive member enables application of a substantially same potential to each of said first outside electrodes; and wherein said second conductive member which is separate from said one conductive member enables application of a substantially same electric potential to each of said second outside electrodes.
