Patent ID: 8267733

Claim:
A method of manufacturing a display unit having a plurality of organic light emitting devices on a substrate, the method comprising the steps of: (a) forming a device substrate by forming a plurality of first electrodes, an auxiliary electrode in a region between the plurality of first electrodes, a projection structure made of an insulating material in a region between the plurality of first electrodes and the auxiliary electrode, and an organic layer covering the plurality of first electrodes and the auxiliary electrode over the substrate; (b) selectively removing a portion of the organic layer formed on the auxiliary electrode; and (c) forming a second electrode on the organic layer and the auxiliary electrode, wherein, the step of selectively removing the portion of the organic layer formed on the auxiliary electrode includes the steps of: (b1) first forming, prior to a removal of the portion of the organic layer formed on the auxiliary electrode, a laminated structure that includes a cover substrate and the device substrate by placing the cover substrate over the device substrate with the projection structure in between in the vacuum atmosphere, (b2) after the step of forming the laminated structure, taking out the laminated structure into the air in a state such that at least a space between the cover substrate and the portion of the organic layer formed on the auxiliary electrode is maintained in the vacuum atmosphere prior to the removal of the portion of the organic layer formed on the auxiliary electrode, (b3) thereafter, while at least the space between the cover substrate and the portion of the organic layer formed on the auxiliary electrode is being maintained in the vacuum atmosphere, irradiating laser light to the laminated structure on a cover substrate side so as to remove the portion of the organic layer formed on the auxiliary electrode, the auxiliary electrode being under the cover substrate while the laser light is being irradiated to remove the portion of the organic layer formed on the auxiliary electrode in the vacuum atmosphere, and (b4) separating the cover substrate and the device substrate after the portion of the organic layer formed on the auxiliary electrode is removed with the laser light.
