sandwiched between said electroluminescent layer and the
electroluminescent layer and anode (Column 29, lines 10-14).
said anode, said hole transport Egusa teaches it is preferable
layer comprising a hole to have low barrier heights in
transport compound having an an organic electroluminescent
energy band intermediate between device for hole and electron
that of said anode and that of injection (abstract, column 17,
said electroluminescent layer, lines 14-47)
wherein said anode Mori discloses that the anode
comprises first and second anode may be ITO (column 28, line
layers, said first anode layer 52). Mori also discloses the
comprising indium tin oxide and use of multiple layer hole
said second anode layer injection layers (column 29,
comprising a material that bonds lines 44-49) and the use of
to indium tin oxide and to said copper phthalocyanine as a hole
transport hole better than said transport layer (example 63,
hole transport compound binds to column 42, lines 60-65) which is
indium tin oxide and said hole part of the anode. This layer
transport layer, said second is between the ITO and any upper
anode layer being sandwiched layer when there are multiple
between said hole transport layers. (column 2, lines 44-
layer and said first anode 49).
layer.
Further, the appellants have not focused any attention on the
examiner’s findings regarding Mori’s example 63. We, like the
examiner, find that this example discloses the claimed first anode
of transparent indium tin oxide (column 3, lines 27-28), covered
with a second anode layer comprising copper phthalocyanine (column
42, lines 60-65), an electroluminescent layer using a thiazole
(column 40, lines 61-63), a hole inhibiting layer, and a cathode
(column 43, lines 1-9). The provision of the hole injecting and
transport layer and the hole inhibiting layer are said to increase
