Flexible display device and method for manufacturing the same

A flexible display device comprising:

• a display panel comprising a bending part which is deformable into a bent shape with respect to a bending axis extending in one direction or has the bent shape;
• and
• a window member disposed on the display panel,
• wherein the window member comprises:
• a first glass substrate;
• an bonding layer disposed on the first glass substrate;
• and
• a second glass substrate disposed on the bonding layer, and
• wherein the bonding layer comprises:
• a first bonding part overlapping the bending part and having a first modulus;
• and
• a second bonding part non-overlapping the bending part and having a second modulus greater than the first modulus.

A method for manufacturing a flexible display device, the method comprising:

• providing a display panel comprising a bending part and a non-bending part;
• providing a window member comprising a first glass substrate, a second glass substrate disposed opposite to the second glass substrate, and a bonding layer disposed between the first glass substrate and the second glass substrate;
• and
• arranging the window member on the display panel,
• wherein the providing the window member comprises:
• providing a first bonding resin and a second bonding resin on the first glass substrate;
• arranging the second glass substrate on the first and second bonding resins;
• and
• curing the first and second bonding resins to form the bonding layer between the first glass substrate and the second glass substrate, and
• wherein
• the first bonding resin is provided in correspondence to the bending part,
• the second bonding resin is provided in correspondence to the non-bending part,
• each of the first bonding resin and the second bonding resin includes a polyol and a isocyanate, and
• the polyol in the first bonding resin has a mean molecular weight less than a mean molecular weight of the polyol in the second bonding resin.
