1. A display device comprising:
an active panel comprising:
a display area comprising a plurality of pixels; and
a non-display area surrounding the display area, the non-display area comprising an adjacent area adjacent the display area and bending areas extending from the adjacent area and spaced from the display area by the adjacent area, the bending areas comprising:
a connection electrode recessed below a surface of the bending areas;
a protective layer covering a part of the connection electrode; and
an opening in the bending areas exposing the connection electrode recessed below the surface through the protective layer; and
a first driving panel coupled with the connection electrode of a first bending area of the bending areas by a first connection member through the opening, and electrically coupled to the active panel, such that the first driving panel is spaced apart from the display area along a first direction parallel to a display surface of the display device and the first connection member is between a bent edge of the first driving panel and the first bending area along the first direction,
wherein each of the bending areas is bent in a second direction perpendicular to a plane formed by the display area, the first connection member coupling the first driving panel with the first bending area at the first bending area that is bent in the second direction, and
wherein the first connection member is configured to couple a first signal from the first driving panel to the active panel through the connection electrode.
