Abstract: A display apparatus includes a display panel and a variable resistance area. The display panel includes a foldable area, a non-foldable area, and a folding axis. The variable resistance area may overlap the foldable area and includes a first resistance part and a second resistance part. The first resistance part has a first resistance when the display panel is folded with a curvature greater than a first curvature and a second resistance different from the first resistance when the display panel is folded with a curvature less than the first curvature. The second resistance part has a third resistance when the display panel is folded with a curvature greater than a second curvature and a fourth resistance different from the third resistance when the display panel is folded with a curvature less than the second curvature. The second curvature may be greater than the first curvature.
