Disclosed is an organic light-emitting display device in which the substrate and the encapsulation substrate are attached to each other by using a frit. The organic light-emitting display device includes a first substrate including a pixel region in which an organic light-emitting diode is formed, and a non-pixel region. The organic light-emitting diode includes an organic light-emitting layer between a first electrode and a second electrode. A second substrate attached to the first substrate. A frit is provided between the non-pixel region of the first substrate and the second substrate to attach the first substrate and the second substrate. A reinforcement material of resin is formed outside the frit.

Organic light-emitting display device with frit seal and reinforcing structure

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.
