Foldable electronic device including plurality of windows
A foldable electronic device is provided. The electronic device includes a flexible display, a first window including a first surface facing the flexible display and a second surface facing the opposite direction to the first surface, the first surface adhered to at least partial region of the flexible display via a first adhesive, and a second window adhered to at least partial region of the second surface of the first window via a second adhesive, in which the first adhesive has a greater thickness than the second adhesive.
1. A portable communication device comprising:
a flexible display;
a housing accommodating the flexible display, the housing including a side portion and a top portion protruded from the side portion;
a first transparent member disposed over the flexible display and foldable according to the flexible display being folded;
a first adhesive layer disposed between the flexible display and the first transparent member, the first adhesive layer having a first thickness;
a second transparent member disposed over the first transparent member and foldable according to the flexible display being folded; and
a second adhesive layer disposed between the first transparent member and the second transparent member, the second adhesive layer having a second thickness smaller than the first thickness,
wherein the flexible display is visible through the first transparent member, the first adhesive layer, the second transparent member, and the second adhesive layer
wherein, when viewed in a direction substantially perpendicular to the flexible display, a first edge portion of the first transparent member is overlapped with and spaced apart from the top portion of the housing, and a second edge portion of the second transparent member is overlapped with and spaced apart from the top portion, and
wherein the first edge portion is spaced apart from the side portion by a first distance, and the second edge portion is spaced apart from the side portion by a second distance which is different from the first distance.
2. The portable communication device of claim 1 , wherein the first adhesive layer has a first adhesive strength, and the second adhesive layer has a second adhesive strength lower than the first adhesive strength.
3. The portable communication device of claim 2 , wherein the second adhesive layer is configured such that, when an external force is applied, the second transparent member is detachable from the first transparent member while the first transparent member remains as attached to the flexible display via the first adhesive layer.
4. The portable communication device of claim 1 , wherein the first edge portion is spaced apart from the side portion by a first distance, and the second edge portion is spaced apart from the side portion by a second distance greater than the first distance.
5. The portable communication device of claim 1 , further comprising an opaque member disposed on the first edge portion such that the opaque member is overlapped with the top portion when viewed in the direction.
6. The portable communication device of claim 1 , further comprising a coating layer disposed on the second transparent member and forming a portion of an external surface of the portable communication device.
7. The portable communication device of claim 6 , wherein the coating layer includes at least one of an anti-fingerprint layer, a hard coating layer, an anti-reflection layer, or an anti-glare layer.
8. The portable communication device of claim 1 , further comprising a coating layer disposed on a surface of the first transparent member facing the second transparent member.
9. The portable communication device of claim 8 , wherein the coating layer includes at least one of an anti-fingerprint layer, a hard coating layer, an anti-reflection layer, or an anti-glare layer.
10. The portable communication device of claim 1 , wherein the first transparent member includes a poly imide (PI) layer.
11. The portable communication device of claim 1 , wherein the second transparent member includes a polyethylene terephthalate (PET) layer.
12. The portable communication device of claim 1 , wherein the first transparent member includes a plurality of polymer layers and the second transparent member includes a single polymer layer.
13. The portable communication device of claim 1 , further comprising a sensor accommodated in the housing such that the sensor is not overlapped with the first transparent member or the second transparent member.
14. The portable communication device of claim 1 , wherein the first transparent member and the second transparent member are configured such that each of the first edge portion and the second edge portion remains as at least partially overlapped with the top portion, when a folding state of the flexible display is changed from an unfolded state to a folded state.
