Abstract
A flexible display device including a well structure. An organic light-emitting element including a pixel electrode, an organic light-emitting layer, and a common electrode is disposed on a substrate. A bank layer is disposed on the pixel electrode, and is disposed to open at least a part of the pixel electrode. Further, at least one well structure is disposed on the bank layer. The well structure disposed on the bank layer can reduce or minimize a delamination phenomenon of an encapsulation layer which can occur due to compressive and tensile stress caused by bending of the flexible display device.
Claims10
A flexible display device, comprising:
- a bank layer and an organic light-emitting element disposed on a flexible substrate;
- and
- an encapsulation layer including a first encapsulation layer, a second encapsulation layer, and a third encapsulation layer that cover the organic light-emitting element,
- wherein the bank layer at least partially defines at least one well structure, and
- wherein the second encapsulation layer includes a first portion and a second portion that are separated from each other resulting in the second encapsulation layer not being continuous and having the first portion and the second portions spaced apart from each other;
- wherein at least two dams are disposed to disconnect the first portion from the second portion, and a third portion of the second encapsulation layer in the well structure has a lower height than the first portion.
A flexible display device, comprising:
- a plurality of organic light-emitting element disposed on a flexible substrate;
- a bank layer on the flexible substrate;
- and
- an encapsulation layer including a first encapsulation layer, a second encapsulation layer, and a third encapsulation layer that cover the organic light-emitting element,
- wherein the bank layer at least partially defines at least one well structure that is located between two light-emitting elements of the plurality of light emitting elements, and
- wherein the second encapsulation layer includes a first portion and a second portion that are separated from each other resulting in the second encapsulation layer not being continuous and having the first portion and the second portion spaced apart from each other;
- wherein portions of the first and the third encapsulation layers on the well structure are adjoined to each other.
A flexible display device, comprising:
- a bank layer and an organic light-emitting element disposed on a flexible substrate;
- and
- an encapsulation layer including a first encapsulation layer, a second encapsulation layer, and a third encapsulation layer that cover the organic light-emitting element,
- wherein the bank layer at least partially defines at least one well structure, and
- wherein the second encapsulation layer includes a first portion and a second portion that are separated from each other resulting in the second encapsulation layer not being continuous and having the first portion and the second portion spaced apart from each other;
- wherein the well structure includes at least two dams spaced apart from each other, and a first dam and a second dam of the at least two dams are located adjacent to the first portion and the second portion, respectively, such that a part of the well structure is located between the first dam and the second dam in a cross-sectional view.
