Abstract

PURPOSE:To improve colour display performance and prevent the reduction of electrical and optical characteristics during life by properly determining the size of the sealed part at least on the side where the coldest point is formed of a luminous bulb. CONSTITUTION:Inside an outer bulb 1, inert gas is sealed. Into a luminous bulb 18, the main electrodes 4 and 7 are inserted which are connected with the outside leads 2 and 5 at both ends of the bulb 18 through molybdenum foils 3 and 6. The size of the sealed part 12 at least on the side where the coldest point is formed of the luminous bulb 18 is set as follows: When the size of the projection surface in the direction of pressing of the sealed part is S cm<2>, and the rated power consumption of the bulb 18 is WLW, 0.0042WL+0.6<=S<=0.005WL+0.9 is formed.
