Abstract
A flexible display may suppress a generation of cracks in an inorganic layer and suppress the spread of cracks. A flexible display includes a flexible substrate and an inorganic layer formed on the flexible substrate. A display unit is formed on the inorganic layer. The display unit includes a plurality of pixels. Each pixel includes an organic light emitting diode. A thin film encapsulation layer covers the display unit. A crack suppressing layer is formed along the edge of the flexible substrate. The crack suppressing layer is disposed on the inorganic layer at an exterior side of the thin film encapsulation layer.
Claims14
A flexible display, comprising:
- a flexible substrate;
- an inorganic layer disposed on the flexible substrate, wherein the inorganic layer comprises a barrier layer, a buffer layer, a gate insulating layer, and an interlayer insulating layer;
- a display unit disposed on the inorganic layer, wherein the display unit includes a plurality of pixels, each pixel thereof including an organic light emitting diode;
- a thin film encapsulation layer covering the display unit;
- and
- a crack suppressing layer formed along an edge of the flexible substrate, wherein the crack suppressing layer is disposed directly on the interlayer insulating layer of the inorganic layer at an exterior side of the thin film encapsulation layer, wherein the crack suppressing layer is configured to contact the edge of the flexible substrate, and the crack suppressing layer is disposed at an uppermost edge of the flexible substrate.
A display device, comprising:
- a flexible substrate;
- an inorganic layer disposed on a portion of the flexible substrate, wherein the inorganic layer comprises a barrier layer, a buffer layer, a gate insulating layer, and an interlayer insulating layer, and wherein a portion of the flexible substrate is not covered by the inorganic layer;
- a thin film encapsulation layer disposed over a display unit, wherein the display unit is disposed on the inorganic layer;
- and
- a crack suppressing layer formed over the portion of the flexible substrate not covered by the inorganic layer, wherein the crack suppressing layer is disposed directly on the inorganic layer and the crack suppressing layer covers a side portion of the inorganic layer comprising the barrier layer, the buffer layer, the gate insulating layer and the interlayer insulating layer, and a top portion of the inorganic layer, wherein the crack suppressing layer is configured to prevent cracks from forming in the inorganic layer during a cutting process, wherein the crack suppressing layer is configured to contact the edge of the flexible substrate, and the crack suppressing layer is disposed at an uppermost edge of the flexible substrate.
