    摘要： A cold cathode fluorescent lamp includes a glass bulb (16), a protective film (22) formed on an inner face of the glass bulb, and a phosphor layer (24) that overlaps the protective film and that contains blue phosphor particles (26B), green phosphor particles (26) and red phosphor particles (26). The glass bulb has been formed from soda glass, and the blue phosphor particles have been coated with a metal oxide (30). Also, the protective film is made of silica (SiO2). Since the protective film has been provided in the fluorescent lamp and since the blue phosphor particles, which readily deteriorate, have been coated with the metal oxide, a good luminance maintenance rate is obtained. In addition, although the glass bulb of the fluorescent lamp is made of soda glass, since the protective film is made of silica, the fluorescent lamp obtains an initial luminance equivalent to the initial luminance of a fluorescent lamp whose glass bulb is made of borosilicate glass.

    摘要： A cold cathode fluorescent lamp has an improved heat dissipation characteristic without an overall increase in size, and a lead wire thereof does not readily break.The cold cathode fluorescent lamp (20) includes electrodes (28 and 30) composed of electrode main bodies (28a and 30a) that are located in an interior of a glass bulb (21), a lead wire (28b and 30b), the glass bulb (21) having ends into which the lead wires are sealed, and a heat dissipater (32 and 34) that is provided on an other portion of the lead wire, the other portion being outside the glass bulb 21. The portion of the heat dissipater surrounding the lead wire (28b and 30b) are in contact with the end surfaces (21c and 21d) of the glass bulb, when viewed externally along an extending direction of the lead wire.

    摘要： The present invention is a backlight unit 1 in which multiple substantially U-shaped lamps, to each of whose respective both end portions 11a and 11b an electrode 12 is attached, are disposed in parallel to one another in an envelope 20 in a manner that the end portions 11a and 11b of each lamp 10 face opposite to the end portions 11a and 11b of the adjacent lamp 10 and are positioned closer to a side wall 42/44 of the envelope 20 than a bent portion 13 of the adjacent lamp 10 is. Herewith, it is possible to offer the backlight unit 1 realizing reduced unevenness in luminance and requiring less power consumption.
