Patent ID: 7312770

Claim:
A substrate used for an image display device, comprising: (A) a first substrate which has a member having a plurality of openings on its surface; (B) light emitters which are arranged in the plurality of openings respectively; (C) a plurality of conductive films arranged to cover the light emitters; and (D) an electrode pad which is connected to a power supply for providing potential to the plurality of conductive films, wherein the member having the plurality of openings has a conductive area, the conductive area is electrically connected to the electrode pad, each of the plurality of conductive films is in contact with the member having the plurality of openings, the minimum value of resistances R x between the two conductive films adjacent to each other in the plurality of conductive films is larger than the minimum value of resistances R z between the conductive area and the plurality of conductive films, and a resistance R p in a range from the conductive area to the electrode pad is smaller than the resistance R z in a range from the conductive area to each of the plurality of conductive films.
