Claims9
A flexible display, comprising:
- a flexible display unit comprising a bending area and a non-bending area adjacent to the bending area;
- and
- a flexible window formed over the flexible display unit and comprising:
- a first film having a first Young's modulus;
- a second film positioned over the first film and having a second Young's modulus that is greater than the first Young's modulus;
- a third film positioned over the second film and having a third Young's modulus that is greater than the second Young's modulus;
- a first adhesive layer interposed between the first film and the second film;
- and
- a second adhesive layer interposed between the second film and the third film,
- wherein the first film has a first portion overlapping the bending area, the second film has a third portion overlapping the bending area and a fourth portion overlapping the non-bending area, and the third film has a fifth portion overlapping the bending area and a sixth portion overlapping the non-bending area,
- wherein the third portion of the second film has a thickness that is less than that of the first portion of the first film,
- wherein the fifth portion of the third film has a thickness that is less than that of the third portion of the second film, and wherein the sixth portion of the third film has a thickness that is greater than that of the fourth portion of the second film.
