Mask and method of manufacturing the same, electro-luminescence device and method of manufacturing the same, and electronic instrument

A mask comprising:

• a first substrate having an opening;
• and
• a second substrate attached to the first substrate and having a plurality of penetrating holes, the penetrating holes set to be perpendicular to a surface of the second substrate, wherein:
• the second substrate is attached to the first substrate such that the penetrating holes are positioned within the opening;
• a groove is formed on at least one of a surface of the first substrate facing the second substrate and a surface of the second substrate facing the first substrate;
• and
• the groove is utilized to form a flow path between the first and second substrates.

A method of manufacturing a mask comprising:

• attaching to a first substrate having an opening a second substrate having a plurality of penetrating holes such that the penetrating holes are positioned within the opening, the penetrating holes set to be tapered;
• forming a groove on at least one of a surface of the first substrate facing the second substrate and a surface of the second substrate facing the first substrate;
• and
• utilizing the groove to form a flow path between the first and second substrates.
