Abstract
An electronic device includes: a display module; a first adhesive member having a multi-layered structure and having a first adhesive surface attached on a back surface of the display module; and a sensing module including a sensing area, the sensing area being attached on a second adhesive surface facing the first adhesive surface of the first adhesive member.
Claims19
An electronic device comprising:
- a display module;
- a first adhesive member having a multi-layered structure and having a first adhesive surface attached on a back surface of the display module;
- a sensing module comprising a sensing area, the sensing area being attached on a second adhesive surface facing the first adhesive surface of the first adhesive member;
- and
- a second adhesive member,
- wherein the first adhesive member comprises:
- a base layer having a size corresponding to the sensing area and comprising a polymer material;
- a first adhesive layer having a size corresponding to the sensing area and being disposed between the base layer and the display module;
- and
- a second adhesive layer between the base layer and the sensing module, and
- wherein the second adhesive member is attached to a side surface of the sensing module, a side surface of the base layer, a side surface of the first adhesive layer, a side surface of the second adhesive layer, and the back surface of the display module,
- wherein the base layer has a modulus in a range of about 150 MPa to about 10 GPa.
