Patent ID: 7952281

Claim:
A lighting device for a display device comprising: a cold cathode tube lamp including: an insulating tube formed of an insulating material that passes light; a first internal electrode provided inside the insulating tube; a second internal electrode provided inside the insulating tube; and a first external electrode provided outside the insulating tube and connected to the first internal electrode so as to be provided with a same potential as a potential of the first internal electrode; a holding jig including: a first conductive member which is an elastic metal member; and an insulating layer; a second conductive member; and a power supply device; wherein the cold cathode tube lamp is arranged to be fed with power from a first conductive member and the second conductive member when the cold cathode tube is mounted with the first conductive member and the second conductive member in a mounted stated; the first external electrode is arranged to be capacitively coupled to the first conductive member when in the mounted state; the first external electrode includes a portion provided on an outer circumferential surface of the insulating tube that is located at a different position than where the first external electrode is connected to the first internal electrode; the insulating layer is arranged on a surface of the first conductive member such that the first conductive member and the first external electrode do not make direct contact with each other when in the mounted state; the holding jig is arranged to hold the first external electrode by an elastic property of the first conductive member; and the power supply device is arranged to supply power to the cold cathode tube lamp through the first conductive member and the second conductive member.
