In addition, the EL display section 6 basically also has the above-mentioned E.
It is constructed in the same way as the L display section 5, and includes an opaque electrode such as an At film that is sequentially laminated on the main surface of the glass substrate 2, an EI layer including a ZnS layer that emits yellow-orange light, an ITO layer, and an ITO layer. It consists of a transparent electrode such as a membrane.

にできないという欠点があった。By the way, in the multicolor EL display device having such a configuration, the narrower the cap G between the pair of glass substrates 1 and 2, the better. 1ffi+11 or less is desirable. However, since each EL display section 5 and 6 is extremely sensitive to moisture, it is usually protected against moisture by enclosing a moisture absorbent such as silica gel in the airtight container 4, but as described above, a pair of glass The space T surrounded by the substrates 1 and 2 is very narrow.
Since a sufficient amount of moisture absorbent cannot be provided, there is a drawback that moisture-resistant protection cannot be provided sufficiently.

るようにしたものである。FIG. 2 is a main cross-sectional view showing a schematic structure of a multicolor EL display device according to an embodiment of the present invention. In the multicolor ET and display device of this embodiment, a pair of glass substrates 1.2 on which EL display portions 5.6 of different emission colors are provided are made to face each other to form an airtight container 4, and these EL display WX5 and 6 are hermetically sealed, similar to the conventional one shown in FIG. The formed back glass 8 as a hearing device is sealed with an adhesive 9, and a moisture absorbing agent 10 such as a sludge is provided in the back glass 8 to form a moisture absorbing portion 11. The space 12 and the space T of the airtight container 4 are communicated through a moisture permeable hole 13 formed at the end of the glass substrate 2.
