Abstract

Disclosed is a manufacturing method of an organic light emitting display device, which allows a frit to be sufficiently fused by illuminating a laser beam such that a width of the laser beam may be above a width of the frit by adjusting power of the laser beam. The manufacturing method of an organic light emitting display device comprises the steps of: a) forming an organic light emitting element comprising a first electrode, an organic thin film and a second electrode on a pixel region of a first substrate divided into the pixel region and a non-pixel region; b) forming a flit along a surrounding of a second substrate corresponding to the non-pixel region; c) arranging the second substrate on an upper side of the first substrate to be superposed to a part of the pixel region and the non-pixel region; and d) attaching the first substrate and the second substrate by illuminating laser beam with a width above a width of the frit from a back surface of the second substrate.

Dependent claims

An organic light emitting display device, comprising:

a first substrate;
a second substrate;
an array of organic light emitting pixels interposed between the first and second substrates;
and
a frit seal comprising a plurality of elongated segments interposed between the first and second substrates, the plurality of elongated segments comprises a first segment;
wherein the plurality of elongated segments in combination surrounds the array, wherein the frit seal, the first substrate and the second substrate in combination enclose the array;
wherein the frit seal comprises a first cross-section taken in a plane perpendicular to an elongation of the first segment;
and
wherein the fit seal is generally homogeneous in color or morphology throughout at least a predetermined first portion of the first cross-section, and
wherein the predetermined first portion of the first cross-section extends across a portion of the first cross-section and is distinct from a second portion of the first cross-section, the first portion having the same composition as the second portion;
wherein the first cross-section further comprises a third portion, the second portion having a uniform makeup and being interposed between the first and third portion, the second portion being distinct from the first and third portions.
