DISCHARGE TUBE FOR SUPPRESSING INFRARED RAY COMMUNICATION INTERFERENCE, LIGHTING APPARATUS FOR DISPLAY UNIT, AND LIQUID CRYSTAL DISPLAY UNIT

摘要

A discharge tube for suppressing an infrared ray communication interference which can suppress an interference in the infrared ray communication, as well as a lighting apparatus for a liquid crystal display unit and a liquid crystal display unit using such a discharge tube. The discharge tube for suppressing an infrared ray communication interference which includes a pair of electrodes has mercury, argon gas, and noble gas with the excitation energy lower than that of the argon gas contained thereinside. An example of the noble gas includes krypton gas. The discharge tube may also contain neon gas thereinside.
