1. A display device comprising:
a substrate comprising a display area, the display area comprising pixel areas each of which comprises a first sub pixel area and a second sub pixel area that are adjacent to each other in a first direction;
an inorganic insulating layer comprising inorganic patterns, each inorganic pattern corresponding to each pixel area comprising the first sub pixel area and the second sub pixel area;
an organic material layer disposed between the inorganic patterns and surrounding each pixel area comprising the first sub pixel area and the second sub pixel area; and
a first conductive line on the inorganic insulating layer, extending in the first direction and crossing pixel areas, wherein
the first conductive line crosses the organic material layer and electrically connects signal lines disposed in each pixel area.
