B2

PROBLEM TO BE SOLVED: To obtain an EL display device with easy manufacture, eliminating the influence of moisture or the like to the utmost, less deterioration with the lapse of time, and capable of keeping the initial performance for a long time by arranging strontium hydride or calcium hydride and strontium hydride as a drying agent within an airtight case in a non-contact state with an organic EL structure.
SOLUTION: This organic EL display device has a sealing plate 3 arranged on an organic EL structure 4 stacked on a board 1 with a specified gap kept; a spacer arranged in a connecting part of the sealing plate 3 to the board 1 at a specified distance between the sealing plate 3 and the board 1; and a sealing adhesive 2 for fixing the sealing plate 3 and sealing the organic EL structure. A drying agent 6 of SrH2 or CaH2 is arranged within the sealed space in a non-contact state with the organic EL structure 4, and inert gas such as Ar, He, or N2 is sealed as sealing gas. The drying agent 6 may be arranged in a recess installed in the sealing plate 3, and may be fixed with a gas or water vapor permeable film sheet 5 or the like.
