Patent ID: 8063561

Claim:
An organic light-emitting display device comprising: a first substrate; an array of organic light-emitting pixels formed over the first substrate; a second substrate placed over the first substrate, the array being interposed between the first substrate and the second substrate; a first frit seal interposed between the first substrate and the second substrate and configured to surround the array; and a second frit seal interposed between the first substrate and the second substrate, spaced apart from the first frit seal, and configured to surround the array; wherein each of the first and second frit seals is attached to the first substrate with or without a material between the frits and the first substrate, and each of the first and second frit seals is also attached to the second substrate with or without a material between the frits and the second substrate, wherein the first frit seal has a height of about 10 μm to about 30 μm, and the height is measured in a direction perpendicular to a surface of the first substrate facing the second substrate, wherein the first frit seal has a width of about 0.5 mm to about 1.5 mm, and the width is measured in a direction parallel to a surface of the first substrate in a cross-sectional plane of the device where the width is the smallest, and wherein the first frit seal is apart from the second frit seal with a distance, and the first frit seal comprises a portion, along which the distance is substantially constant, and wherein in the portion along which the distance is substantially constant, the distance is from about 10 μm to about 1000 μm.
