Display device comprising encapsulation structure and method of manufacturing the same
A display device includes a substrate, a light-emitting element layer disposed on the substrate, a first encapsulation layer and a second encapsulation layer which are disposed on the light-emitting element layer, and a buffer layer which covers the first encapsulation layer and the second encapsulation layer. The second encapsulation layer includes a first film, a second film disposed on the first film, and a third film disposed between the first film and the second film, and a side surface of the third film is disposed more inward than a side surface of the first film and a side surface of the second film.
1 . A display device comprising:
a substrate;
a light-emitting element layer disposed on the substrate;
a first encapsulation layer and a second encapsulation layer, which are disposed on the light-emitting element layer;
a third encapsulation layer disposed between the first encapsulation layer and the second encapsulation layer; and
a buffer layer which covers the first encapsulation layer and the second encapsulation layer,
wherein the second encapsulation layer includes a first film, a second film disposed on the first film, and a third film disposed between the first film and the second film, and
an end portion of the third film is disposed more inward than an end portion of the first film and an end portion of the second film, wherein
a first region is defined as a region between an end of the third film and an end of the first film,
a second region is defined as a region between an end of the buffer layer and the end of the third film,
wherein a length of the second region in one direction is defined by the following equation:
L A2 −L TSA −L TA2 +L A1
( L TA1 ≥L TA2 ≥L TA3 ),
wherein
L A2 denotes the length of the second region in the one direction,
L A1 denotes a length of the first region in the one direction,
L TBA denotes a length of the buffer layer in the one direction,
L TA1 denotes a length of the first encapsulation layer in the one direction,
L TA2 denotes a length of the second encapsulation layer in the one direction, and
L TA3 denotes a length of the third encapsulation layer in the one direction.
2 . The display device of claim 1 , wherein the length of the first region in the one direction is smaller than the length of the second region in the one direction.
3 . A display device comprising:
a substrate;
a light-emitting element layer disposed on the substrate;
a first encapsulation layer and a second encapsulation layer, which are disposed on the light-emitting element layer;
a third encapsulation layer disposed between the first encapsulation layer and the second encapsulation layer; and
a buffer layer which covers the first encapsulation layer and the second encapsulation layer,
wherein the second encapsulation layer includes a first film, a second film disposed on the first film, and a third film disposed between the first film and the second film, and
an end portion of the third film is disposed more inward than an end portion of the first film and an end portion of the second film, wherein
a thickness of the third encapsulation layer is greater than a thickness of the first encapsulation layer and a thickness of the second encapsulation layer, and
the third encapsulation layer and the second film include different carbon compounds from each other.
