Title:
INORGANIC EL ELEMENT
Document Type and Number:
Japanese Patent JP2001250691
Kind Code:
A
Abstract:
To obtain an inorganic EL element having a structure which enables further improvement in high luminosity, among an inorganic EL element using a thick-film insulation layer.
In the inorganic EL element of double insulation-layer type which has a luminescence layer between a first insulation layer and a second insulation layer, the composition of the inorganic EL element is characterized by the fact that the dielectric constant of the insulation layer of the above first is 500 or more, and the relation between the capacity C1 of the capacitor of the first insulated layer and the capacitance C 2 of the capacitor of the second insulation layer is 1.5>C1/C2>0.5.
