Abstract
Disclosed is an organic light emitting display device which may improve reliability. The organic light emitting display device includes light emitting elements arranged in an active area, crack prevention layers arranged in a non-active area along the perimeter of the active area, and at least one crack detection line arranged between the active area and the crack prevention layers, and judges whether or not a crack is generated through an output resistance value from the at least one crack detection line and may thus raise yield.
Claims19
An organic light emitting display device comprising:
- light emitting elements positioned in an active area of the display device;
- a crack prevention layer positioned in a non-active area of the display device, the non-active area positioned adjacent to a perimeter of the active area;
- at least one crack detection line positioned between the active area and the crack prevention layer;
- at least one dam surrounding the active area;
- and
- a power line positioned inwardly from the at least one dam,
- wherein the at least one crack detection line is positioned between the dam and the crack prevention layer, and
- wherein the power line is positioned to not overlap with the at least one dam.
An organic light emitting display device comprising:
- light emitting elements positioned in an active area of the display device;
- a crack prevention layer positioned in a non-active area of the display device, the non-active area positioned adjacent to a perimeter of the active area;
- at least one dam surrounding the active area;
- and
- at least one crack detection line positioned not to overlap with the at least one dam between the active area and the crack prevention layer;
- wherein the at least one crack detection line surrounds at least three sides of the active area, and
- wherein the at least one crack detection line is formed of the same material as at least one of the gate electrode, the source electrode or the drain electrode of the driving transistor, on the same layer as the at least one of the gate electrode, the source electrode or the drain electrode of the driving transistor.
