30. An OLED comprising: Mori teaches organic LED (column
3, lines 26-27)
a cathode comprising a Mori teaches a cathode for
first conductive layer; injecting electrons (column 3,
lines 25-26) of metal (column
28, lines 59-62)
an electroluminescent layer Mori teaches an
comprising an oxadiazole, electroluminescent layer (column
thiadiazole or triazole 4, lines 8-11) which may include
compound, said oxadiazole, an oxadiazole hole-moving
thiadiazole or triadiazole element (column 4, lines 42-43)/
compound emitting light when
holes and electrons recombine
therein;
an anode comprising a Mori discloses a conducting
second conducting layer, wherein anode which may be transparent
said anode is transparent to (column 28, lines 47-50)
light generated by said
electroluminescent layer; and
a hole transport layer, Mori discloses a hole transport
said hole transport layer being layer between the
