Organic light emitting display device
First Claim
1. 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 μ
m to about 30 μ
m, 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, andwherein 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 μ
m to about 1000 μ
m.

Abstract
Disclosed is an organic light-emitting display device comprising: a pixel region wherein an organic light-emitting device comprised of a first electrode, an organic thin film layer and a second electrode is formed; a first substrate comprising a non-pixel region encompassing the pixel region; a second substrate disposed on the upper of the first substrate to be overlapped with the pixel region and a portion of the non-pixel region; and a plurality of frits provided between the first substrate and the second substrate and formed in parallel at spaced intervals along the peripheral portion of the pixel region, wherein the first substrate is bonded to the second substrate by the plurality of frits. Even in the case that a portion of the frit is delaminated due to a partial defection thereof, its encapsulation state can be maintained as it is by being encapsulated with the frit in a multi structure and even in the case that a substrate with a large diameter is used, the width and height of the frit do not need to increase.
