Classification: CPC G  H  Y | IPC G  H

Claim 12:
13. A foldable display device, comprising:
a display panel including a folding area and non-folding areas on both sides of the folding area;
a back plate disposed under the display panel;
a first support layer disposed under the back plate; and
an opening pattern included in the first support layer, the opening pattern arranged in a portion corresponding to the folding area,
wherein the back plate and the first support layer are spaced apart from each other, and
wherein the display panel includes:
a flexible substrate;
a thin film transistor disposed on the flexible substrate, the thin film transistor including a gate electrode, source electrode, a drain electrode, and a semiconductor layer;
a first planarization layer on the thin film transistor;
a second planarization layer sequentially stacked on the first planarization layer;
a light emitting element disposed on the second planarization layer, the light emitting element including an anode, a light emitting unit, and a cathode; and
an intermediate electrode on the first planarization layer, the intermediate electrode coupled to the drain electrode of the thin film transistor through a contact hole formed in the first planarization layer and coupled to the anode through a contact hole in the second planarization layer.
