A method for patterning an organic light-emitting device having an organic light-emitting layer underlying an electrode layer, the method comprising: a first patterning step, in which the electrode layer is patterned by exposure to a laser beam so as to remove part of the depth of the electrode layer in the areas patterned by the laser beam; and a second patterning step in which the remaining depth of the electrode layer is removed in the areas patterned during the first step, the second patterning step being of a type to which the organic layer is less sensitive than that of the first patterning step. |
