A display device (10, 20), comprising: a substrate having an inner-side surface and an outer-side surface opposite to the inner-side surface, the substrate including a display front portion, a display curved portion extending from the display front portion, a non-display curved portion (130, 150, 160, 170) extending from the display curved portion, and a non-display rear portion extending from the non-display curved portion (130, 150, 160, 170); the non-display rear portion facing the display front portion and being spaced apart from the display front portion so as to face the inner-side surface of the substrate; a display layer attached to the display front portion and the display curved portion; a member attached to the inner-side surface of the substrate, and including one or several articulations attached to the inner-side surface of the non-display curved portion (130, 150, 160, 170); and a window attached to an outer side of the display layer; wherein the display layer is attached to the outer-side surface of the substrate, at least a portion of the display curved portion forms a first generally curved surface, at least a portion of the non-display curved portion (130, 150, 160, 170) forms at least a second generally curved surface (132, 152, 162, 172) which is bent toward the inner-side surface of the substrate, the second generally curved surface (132, 152, 162, 172) has a generally curved shape that gradually connects a plane formed by the display curved portion and a plane formed by the non-display rear portion, the non-display rear portion forms a substantially flat surface, at least one of the articulations has a cross-sectional width (314, 324, 354, 364, 374) that decreases in a direction away from the substrate, and at least one of the articulations contacts another articulation or an adjacent inner sidewall of the member to form the second generally curved surface (132, 152, 162, 172) of the non-display curved portion (130, 150, 160, 170). a substrate having an inner-side surface and an outer-side surface opposite to the inner-side surface, the substrate including a display front portion, a display curved portion extending from the display front portion, a non-display curved portion (130, 150, 160, 170) extending from the display curved portion, and a non-display rear portion extending from the non-display curved portion (130, 150, 160, 170); the non-display rear portion facing the display front portion and being spaced apart from the display front portion so as to face the inner-side surface of the substrate; a display layer attached to the display front portion and the display curved portion; a member attached to the inner-side surface of the substrate, and including one or several articulations attached to the inner-side surface of the non-display curved portion (130, 150, 160, 170); and a window attached to an outer side of the display layer; wherein the display layer is attached to the outer-side surface of the substrate, at least a portion of the display curved portion forms a first generally curved surface, at least a portion of the non-display curved portion (130, 150, 160, 170) forms at least a second generally curved surface (132, 152, 162, 172) which is bent toward the inner-side surface of the substrate, the second generally curved surface (132, 152, 162, 172) has a generally curved shape that gradually connects a plane formed by the display curved portion and a plane formed by the non-display rear portion, the non-display rear portion forms a substantially flat surface, at least one of the articulations has a cross-sectional width (314, 324, 354, 364, 374) that decreases in a direction away from the substrate, and at least one of the articulations contacts another articulation or an adjacent inner sidewall of the member to form the second generally curved surface (132, 152, 162, 172) of the non-display curved portion (130, 150, 160, 170). at least a portion of the display curved portion forms a first generally curved surface, at least a portion of the non-display curved portion (130, 150, 160, 170) forms at least a second generally curved surface (132, 152, 162, 172) which is bent toward the inner-side surface of the substrate, the second generally curved surface (132, 152, 162, 172) has a generally curved shape that gradually connects a plane formed by the display curved portion and a plane formed by the non-display rear portion, the non-display rear portion forms a substantially flat surface, at least one of the articulations has a cross-sectional width (314, 324, 354, 364, 374) that decreases in a direction away from the substrate, and at least one of the articulations contacts another articulation or an adjacent inner sidewall of the member to form the second generally curved surface (132, 152, 162, 172) of the non-display curved portion (130, 150, 160, 170).
