PURPOSE:To release the water and vapor occuring in the course of manufacture and prolong the lifetime by furnishing a non-indication part with a specific adsorbent. CONSTITUTION:An adsorbing layer 5 consisting of zeolite is furnished in the non-indication part of a DC type electroluminescence element, and thereby the water and vapor generated at a high temp. due to heat emission at the time of foaming during manufacture are released out of the adsorbent. Thus fluorescent substance 2 is prevented from deterioration, and a long lifetime is accomplished. |
