1. A flexible display device comprising:
a flexible display panel comprising a folding area and a peripheral area; and a first outer member on a surface of the flexible display panel and comprising a first groove pattern extending in a first direction at the folding area, wherein the first groove pattern comprises:
a first inclined portion having a first surface inclined to the surface of the display panel; anda second inclined portion spaced apart from the first inclined portion in a second direction crossing the first direction, the second inclined portion having a second surface inclined to the surface of the display panel, wherein a width of the first groove pattern satisfies the Formula
W=F+(S1+S2)=π×R and wherein W denotes the width of the first groove pattern, F denotes a distance between the first inclined portion and the second inclined portion in the second direction, S1 denotes a width of the first inclined portion in the second direction, S2 denotes a width of the second inclined portion in the second direction, it denotes a circular constant, and R denotes a radius of curvature of the flexible display panel at the folding area. |
