Abstract
A display device includes a window including a planar portion and a bending portion that is bent from the planar portion. A display module is disposed below the window. The display module includes a central portion overlapping the planar portion and an edge portion overlapping the bending portion. An adhesive member including an adhesive layer is disposed between the window and the display module. A lubrication layer overlaps at least a portion of the adhesive layer.
Claims14
A method for bonding a display device, the method comprising:
- disposing a display substrate, comprising a central portion and an edge portion adjacent to the central portion, on a pad disposed on a stage;
- forming a lubrication layer on the display substrate;
- forming an adhesive layer on the lubrication layer;
- providing a window substrate comprising a planar portion and a bending portion that is bent from the planar portion;
- aligning the window substrate with the display substrate;
- attaching the adhesive layer to the window substrate;
- and
- applying heat to the adhesive layer,
- wherein viscosity of the adhesive layer increases during a first period for which a temperature of the adhesive layer increases from a first temperature to a second temperature.
A method for bonding a display device, the method comprising:
- providing a window substrate comprising a planar portion and a bending portion that is bent from the planar portion;
- forming a first lubrication layer on a rear surface of the window substrate;
- disposing a display substrate, comprising a central portion and an edge portion adjacent to the central portion, on a pad disposed on a stage;
- forming an adhesive member, comprising an adhesive layer and a second lubrication layer, on the display substrate;
- attaching the central portion to the planar portion;
- and
- attaching the edge portion to the bending portion,
- wherein the first lubrication layer formed on the window substrate comes into direct contact with the adhesive member.
