Electronic board and manufacturing method thereof, electro-optical device, and electronic apparatus

1. An electronic board, comprising:

a substrate having a surface on which electrode sections are disposed in a row along a first direction;

a resin member provided on the surface of the substrate and adjacent to the electrode sections, the resin member extending in at least the first direction; and

a wiring pattern provided on the surface of the substrate and electrically connected to the electrode sections, wherein

the wiring pattern includes:

a first conductive film extending in at least a second direction that intersects the first direction, the first conductive film covering one of the electrode sections and a part of the resin member;

a second conductive film extending in at least the second direction, the second conductive film covering another one of the electrode sections and another part of the resin member;

a first terminal formed by a part of the first conductive film that covers the part of the resin member;

a second terminal formed by a part of the second conductive film that covers the another part of the resin member;

a connecting section that electrically connects the first and second conductive films; and

a resistance element having conductivity, the resistance element being a part of the connecting section, and wherein

the first conductive film and the second conductive film each have a double layer configuration including a first film and a second film laminated on the first film;

the second film is a different material than the first film;

the first film connects:

the one of the electrode sections and the part of the resin member; and

the another one of the electrode sections to the another part of the resin member; and

the connecting section has:

a double layer configuration at both ends thereof including the first film and the second film laminated on the first film; and

a single layer configuration including the first film but not the second film at the part of the connecting section forming the resistance element.

2. The electronic board according to claim 1 , wherein the resin member comprises an elastic resin material.

3. The electronic board according to claim 1 , wherein the first and second terminals are disposed between the resistance element and the electrode sections in the second direction.

4. The electronic board according to claim 1 , wherein the resistance element is sealed by a sealing material.

5. The electronic board according to claim 1 , further comprising:

a semiconductor element; and

wherein at least one of the electrode sections is an external terminal of the semiconductor element.

6. An electro-optical device on which the electronic board according to claim 1 is mounted.

7. An electronic apparatus comprising the electronic board according to claim 1 .

8. The electronic board according to claim 1 , wherein the material of the first film has a resistance value that is higher than that of the material of the second film.
