Abstract
An organic light emitting display device which includes a base member; an organic light emitting display unit disposed on the base member and configured to generate an image; a sealing layer configured to seal the organic light emitting display unit; a capping substrate disposed on the sealing layer and having a plurality of metal layers, one of the metal layers being in contact with the sealing layer and having at least one groove; and a moisture absorbent provided in the groove.
Claims13
An organic light emitting display device comprising:
- a base member;
- an organic light emitting display unit disposed on the base member and configured to generate an image;
- a sealing layer configured to seal the organic light emitting display unit, the sealing layer overlapping the organic light emitting display unit;
- a capping substrate disposed on the sealing layer and having a first metal layer, a second metal layer and a third metal layer, each of the first second and third metal layers overlapping the organic light emitting display unit, the first metal layer being in contact directly with the sealing layer and having at least one groove, wherein the first metal layer includes stainless steel, titanium, or titanium alloy, the second metal layer includes aluminum or aluminum alloy and the third metal layer includes the same matter as the first metal layer;
- and
- a moisture absorbent provided in the groove,
- wherein the second metal layer is disposed between the first metal layer and the third metal layer, and
- a heat transmission rate of the second metal layer is higher than a heat transmission rate of each of the first and third metal layers.
An organic light emitting display device comprising:
- a base member in which a display area including a plurality of pixel regions and a non-display region adjacent to at least a part of the display area are defined;
- an organic light emitting element including a first electrode, a second electrode opposite to the first electrode, and an organic light emitting layer interposed between the first electrode and the second electrode, the organic light emitting element being provided at each of the plurality of pixel regions, respectively;
- a capping substrate disposed to be opposite to the base member and including a first metal layer, a second metal layer and a third metal layer being stacked sequentially such that each of the first, second and third metal layers overlaps the organic light emitting element, the first metal layer having at least one groove, wherein the first metal layer includes stainless steel, titanium, or titanium alloy, the second metal layer includes aluminum or aluminum alloy and the third metal layer includes the same matter as the first metal layer;
- a moisture absorbent provided in the groove;
- and
- a sealing member provided between the base member and the capping substrate to seal the organic light emitting element, the sealing member being in contact directly with the first metal layer,
- wherein a heat transmission rate of the second metal layer is higher than a heat transmission rate of each of the first and third metal layers.
