Title:
ORGANIC EL PANEL
Document Type and Number:
Japanese Patent JP3743005
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide an organic EL panel capable of extending a service life for emitting light over a long time with predetermined luminance even when it is driven in a high-current density region.
SOLUTION: This organic EL panel is composed by forming an organic EL element composed by catching an organic layer 5 having at least a luminescent layer 5c with a pair of electrodes on a translucent support substrate. The luminescent layer 5c is formed by adding a fluorescent material 5g and a transportation material 5h as guest materials to a host material 5f. For the transportation material 5h, mobility of positive holes or electrons is above 10-4cm2/V×s.
