Abstract
A lead-free glass material for sealing organic EL elements is provided with which satisfactory sealing quality is obtained through laser sealing without requiring the addition of a metallic powder. The lead-free glass material for sealing organic EL elements has a glass composition which comprises, in terms of mol %, 30-60% VO, 5-20% ZnO, 5-20% BaO, 15-40% TeO, 0-7% NbO, 0-7% AlO, 0-5% SiO, 0-5% MgO, 0-5% SbO, 0-4% CuO, and 0-4% SnO and in which NbO+AlOis 0.5-10%, SiO+MgO+SbOis 0-5%, and CuO+SnO is 0-4%. The glass material has low-temperature softening properties, melt stability, and a low coefficient of thermal expansion and is inhibited from thermally adversely affecting organic EL elements The glass material can attain high sealing properties and high sealing strength in high yield.
