## Abstract

A flexible display apparatus including: a first film including a first surface and a second surface that are opposite each other, and a first groove formed in the first surface, the first film having a first rigidity; a third film on the second surface of the first film; a fourth film facing the third film; an emission display unit between and encapsulated by the third film and the fourth film; and a second film on the fourth film and facing the first film, the second film having a second rigidity that is less than the first rigidity.

## Claims

### Claim 1

A flexible display apparatus comprising:
a first film including a first region, a second region, and a bending portion between the first region and the second region, a plurality of first openings or grooves being defined in the bending portion of the first film;
a third film over the first film, the third film including a bending portion corresponding to the bending portion of the first film;
a fourth film over the third film, the fourth film including a bending portion corresponding to the bending portion of the first film;
an emission display unit between the third film and the fourth film;
an elastic member disposed in correspondence with the bending portion of the third film; and
a second film over the fourth film, the second film including a first surface adjacent to the fourth film, a second surface opposite to the first surface, and a second opening or groove defined in the second surface.
