▎ 摘　　要

NOVELTY - Manufacturing graphene film, comprises preparing a graphite catalytic layer pattern including a base unit and a protrusion part partly protruded from one side of the base unit, and supplying a carbon-based material to the graphite catalytic layer pattern. USE - The method is useful for manufacturing graphene film (claimed), which is useful in different flexible devices of electrodes such as organic LED and display device such as organic light emitting display device having organic field effect transistor, and useful as electrode in solar device. ADVANTAGE - The method prepares the graphene film with three dimensional structure, optical transparency and flexibility, excellent optical permeability, excellent electric conductance and improved electrical characteristic.
