A display device includes linear structures each having a first conductor linearly extended and a light emitting layer structure which covers at least a part of the conductor, the linear structures being arranged in parallel. The linear structures are electrically insulated by first insulating portions from one another. Second conductors are arranged in parallel so as to cross the linear structures and electrically connected to the light emitting layer structures at crossing portions arranged in a matrix. The linear conductors are electrically insulated by the linear conductors from one another.
