Abstract

PURPOSE: To prevent a noise wave, while interrupting a leakage of a high frequency power, by forming a reflective plate behind a fluorescent lamp by a metal plate and a non-conductive coating with its front surface covered by a non-conductive film. CONSTITUTION: A non-conductive coating is provided by adhesively coating a non-conductive reflective film 56 on the front surface of a metal plate 55 and by coating the surface of the reflective film 56 with a non-conductive translucent film 57. Thereby, electric field by a high frequency current of a lamp 4 is interrupted and an induction current is not sent to the metal plate 55 in order to prevent a leakage of a lighting current, and in addition, noise radiated from a lighting circuit and a lamp 4 is shielded by the metal plate 55, in order to prevent an optical image of a liquid crystal being inconveniently disturbed.
