That is, on the right side of a nine-segment electrode coated with a phosphor having a blue emission spectrum, a quadrupole segment coated with a phosphor having a green emission spectrum is placed.
On the right side of the 9-segment electrode again! The segments coated with a phosphor having an emission spectrum of Above and below the nine-segment cap is a phosphor coating 4 with a green emission spectrum.
A segment electrode is placed on the left and right sides of which are coated with a fluorescent material having a red emission spectrum, and a segment electrode is placed on the left and right sides of the segment electrode, and the edges are red.

する場合よりも゛、面平均輝度の向上を図れる。Arrange the edges, red, etc. alternately. As can be seen from the above description, in the present invention, the number of light emitting segments on the edges is 1:2, which is twice the number of light emitting segments on the back or red. The luminescence intensity of a phosphor with an edge emission spectrum, which is generally used in a fluorescent display tube, is more than 7 orders of magnitude higher than the luminance of a phosphor with a red emission spectrum.・By using twice the number of light-emitting segments on the edge as blue and red light-emitting segments as in the present invention, the edge s f has a surface area larger than when the same number of red light-emitting segments is arranged. Average brightness can be improved.
