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 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 therebetween, and wherein each of the first and second frit seals is also attached to the second substrate with or without a material therebetween.

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.

19. A method of making an organic light-emitting display device, the method comprising:
-
providing an unfinished device comprising a first substrate and an array of organic light emitting pixels formed over the first substrate; providing a second substrate; interposing the array between the first and second substrates; interposing a first frit between the first and second substrates while surrounding the array; interposing a second frit between the first and second substrates while surrounding the array; and melting and solidifying at least part of the first and second frits so as to interconnect the first substrate and the second substrate via the first and second frits. - View Dependent Claims (20, 21, 22, 23, 24, 25, 26)
