Method of manufacturing organic EL device and organic EL device
View Patent ↗Provided is a method of manufacturing an organic EL device, wherein a device which has a cathode, an anode facing the cathode, and an organic layer is disposed between the cathode and the anode is provided, a pulsed laser is transmitted through the cathode and is irradiated to the organic layer, and a conductive part having an electrical resistance value lower than that of the organic layer is formed in the organic layer.
1. An organic EL device comprising:
a first electrode;
a second electrode that faces the first electrode;
an organic layer which is disposed between the first electrode and the second electrode and has a first electrical resistance value; and
a conductive part which is disposed in the organic layer and has a second electrical resistance value lower than the first electrical resistance value,
wherein the conductive part is the organic layer which has carbonized.
2. An organic EL device comprising:
a first electrode;
a second electrode that faces the first electrode;
an organic layer which is disposed between the first electrode and the second electrode and has a first electrical resistance value; and
a conductive part which is disposed in the organic layer and has a second electrical resistance value lower than the first electrical resistance value,
wherein the conductive part is formed by irradiating the organic layer with a pulsed laser having a pulse width at least equal to 1 fsec and no greater than 1,000 psec, and having energy at least equal to 30 nJ and no greater than 60 nJ.
3. The organic EL device of claim 1 ,
wherein the conductive part does not contact the first electrode and the second electrode.
4. An organic EL device comprising:
a first electrode;
a second electrode that faces the first electrode;
an organic layer which is disposed between the first electrode and the second electrode and has a first electrical resistance value; and
a conductive part which is disposed in the organic layer and has a second electrical resistance value lower than the first electrical resistance value,
wherein the conductive part is in a portion of the organic layer having a greatest thickness.
5. An organic EL device comprising:
a first electrode;
a second electrode that faces the first electrode;
an organic layer which is disposed between the first electrode and the second electrode and has a first electrical resistance value; and
a conductive part which is disposed in the organic layer and has a second electrical resistance value lower than the first electrical resistance value,
wherein the organic layer has a non-light emitting part, and
the conductive part is in a position different from the non-light emitting part.
