1. A display device having a bendable region and a non-bendable region arranged in a first direction, the display device comprising:
a substrate including an organic material;
a barrier layer disposed on the substrate;
an active pattern disposed on the barrier layer in the non-bendable region;
a first inorganic insulating layer disposed on the barrier layer and the active pattern;
a first conductive pattern disposed on the first inorganic insulating layer in the non-bendable region;
a second inorganic insulating layer disposed on the first conductive pattern and the first inorganic insulating layer;
a second conductive pattern disposed on the second inorganic insulating layer in the non-bendable region;
a third inorganic insulating layer disposed on the second conductive pattern and the second inorganic insulating layer;
a third conductive pattern disposed on the third inorganic insulating layer in the non-bendable region; and
a conductive layer disposed in the non-bendable region and the bendable region, a portion of the conductive layer being disposed on the same layer as that of the third conductive pattern in the non-bendable region,
wherein:
a stacked structure of the barrier layer and the first to third inorganic insulating layers has an opening to expose a portion of the substrate in the bendable region; and
the conductive layer extends from the non-bendable region to the bendable region, and contacts the organic material of the exposed portion of the substrate in the bendable region.
