An organic EL device has an anode, a cathode, and a polymer luminescent
layer disposed between the anode and the cathode, and contains a host
molecule and a luminescent dye molecule, the host molecule being formed of
a .pi.-electron conjugated polymer having a carbon-fluorine bond, at least
one type of luminescent dye molecule being selected from the group
consisting of a transition metal complex and a linear .pi.-electron
conjugated molecule.
