Organic light-emitting display device and method for fabricating the same

An organic light-emitting device comprising:

• a first substrate;
• a second substrate;
• an array of light-emitting pixels interposed between the first and the second substrates, wherein the second substrate is thinner in an inner portion opposite the array than in an outer portion surrounding the inner portion;
• and
• a frit layer formed over the inner and the outer portions of the second substrate facing the first substrate such that the frit layer over the inner and outer portions in combination with the first substrate form an enclosed space where the array is located, wherein the first substrate and the second substrate are adhered to each other by the frit layer in the outer portion.

A method of making an organic light-emitting device, the method comprising:

• providing an unfinished device comprising a first substrate and an array of organic light emitting pixels;
• providing a second substrate, a frit layer and a peripheral frit, wherein the frit layer is formed over a surface of the second substrate, wherein the peripheral frit surrounds the frit layer and is connected to the frit layer;
• placing the second substrate over the unfinished device such that the array is interposed between the first substrate and the frit layer, wherein after placing the peripheral frit surrounds the array;
• and
• melting and resolidifying at least part of the peripheral frit so as to interconnect the unfinished device and the second substrate via the peripheral frit.
