Abstract
A display device includes: a substrate including a first area, a second area, and a bending area between the first area and the second area; a display layer disposed on the first area of the substrate; a display driving unit disposed on the second area of the substrate; and a cover member including a first surface and a second surface and extending to cover a portion of the second area of the substrate, the bending area of the substrate, and a portion of the first area of the substrate, the cover member including a separation area in which the cover member is partially separated on the first surface opposite to the second surface facing the substrate.

A display device comprising:
- a substrate comprising a first area, a second area, and a bending area between the first area and the second area;
- a display layer disposed on the first area of the substrate;
- a display driving unit disposed on the second area of the substrate;
- and
- a cover member that comprises a metal material and is spaced apart from the display layer, the cover member comprising a first surface and a second surface and extending to cover a portion of the second area of the substrate, the bending area of the substrate, and a portion of the first area of the substrate such that the cover member comprises a first distal end in the first area as seen in side view and a second distal end in the second area as seen in side view, wherein
- the cover member comprises a separation area in which the cover member is partially separated on the first surface opposite to the second surface facing the substrate, the separation area comprising a plurality of recessed portions and being spaced apart from the first distal end and the second distal end of the cover member, the separation area having a thickness less than a thickness of the cover member at a center portion of the cover member and at the first and second distal ends of the cover member,
- wherein the plurality of recessed portions comprise a first recessed portion closest to the display layer and a second recessed portion closest to the display driving unit,
- wherein each of the first and second recessed portions comprises an inner concave portion, a middle concave portion, and an outer concave portion,
- wherein the inner concave portion, the middle concave portion, and the outer concave portion of the first recessed portion are aligned with the inner concave portion, the middle concave portion, and the outer concave portion of the second recessed portion in a thickness direction of the substrate when the bending area is in a bent state, and
- wherein the middle concave portion of the first recessed portion and the middle concave portion of the second recessed portion are vertically aligned with a bending axis of the bending area of the substrate in the thickness direction of the substrate when the bending area is in the bent state.
