An illumination device includes: a substrate; a first transparent electrode covering approximately an entire surface of a display region of the substrate; a second transparent electrode which overlaps with the first transparent electrode when seen in plan view and covers approximately the entire surface of the display region; and a plurality of island shaped light emitting elements disposed between the first transparent electrode and the second transparent electrode. The first and second transparent electrodes are formed as single continuous films.

A method of forming a mask, in which a film pattern is formed on a substrate by using a mask, includes sequentially arranging the mask, the substrate and a first member having a flat surface contacting with the substrate in this order from a supply source of film forming material; and attracting the mask and the first member by means of a magnetic force.

Method of forming mask and mask

A through hole tapered from an opening to the in-depth direction is formed in a semiconductor substrate provided with an integrated circuit. An insulating material is supplied to the through hole through the opening so as to form an insulating layer on the inner surface of the through hole. A conductive material is supplied through the opening to the through hole provided with the insulating layer so as to form a conductive portion inside the insulating layer.
