Cold cathode fluorescent lamp and back-light emitting device and note-type personal computer with said lamp

摘要

There is provided a cold cathode fluorescent lamp (50) including a transparent tube (35) having first and second light-emitting areas (37a,37b) defined by partitioning an inner space of the transparent tube at the center, first and second terminal electrodes (31,34) positioned in the first and secon d light-emitting areas, respectively, first and second intermediate electrodes (32,33) positioned in the first and second light-emitting areas, and facing the first and second terminal electrodes, respectively, first and second lead-in wires (36a,36b) connected to the first and second terminal electrodes, respectively, and lead-in wires (36c,36d) connected to the first and second intermediate electrodes. The above-mentioned cold cathode fluorescent lamp makes it possible to lower a break-down voltage and a discharge voltage down to about halves of them in a conventional fluorescent lamp, and hence, discharged electrons are not attracted to a metal part.
