Method of manufacturing organic electroluminescent panel, organic electroluminescene device, and mask

A method of manufacturing an organic electroluminescent panel, the method including:

• forming a first electrode on a substrate;
• forming spacers protruding in a direction perpendicular to a surface of the substrate;
• forming an organic luminescent layer over the first electrode by placing a mask while a surface thereof is brought into contact with the spacers;
• and
• forming a second electrode over the organic luminescent layer.

A method of manufacturing an organic electroluminescent panel, the method including:

• forming a first electrode on a substrate;
• forming an organic luminescent layer over the first electrode by placing a mask, which has spacers protruding in a direction perpendicular to a surface of thereof, above the substrate;
• and
• forming a second electrode over the organic luminescent layer.

An organic electroluminescent device, comprising:

• a first electrode formed on a substrate;
• spacers protruding in a direction perpendicular to a surface of the substrate at an outside of a luminescent region on the substrate;
• an organic luminescent layer formed over the first electrode within the luminescent region on the substrate;
• and
• a second electrode formed over the organic luminescent layer.

A method of manufacturing an organic electroluminescent panel, the method including:

• forming a first electrode within each of a plurality of panel regions on a substrate;
• forming spacers protruding in a direction perpendicular to a surface of the substrate;
• forming an organic luminescent layer over the first electrode by placing a mask while a surface thereof is brought into contact with the spacers;
• forming a second electrode over the organic luminescent layer;
• and
• dividing the substrate into the respective panel regions.
