A cover unit for use for a display device, comprising: a first base member disposable on a display device; a color layer on the first base member, the color layer implementing a color of the cover unit; a reflective layer; a pattern layer including a pattern on one surface of the pattern layer that makes contact with the reflective layer, the pattern layer being disposed on the color layer and the reflective layer being disposed on the pattern layer, the reflective layer having an intrinsic color determined by a material forming the reflective layer, wherein the first base member comprises a first area and a second area defined therein when viewed in a plan view, and each of the reflective layer and the color layer is overlapped with the first area and not overlapped with the second area when viewed in a plan view, wherein the reflective layer has a second color, and the color layer has a third color, the first area has a first color when viewed in a plan view by optically combining the second color of the reflective layer and the third color of the color layer, and the cover unit is configured such that a light incident from the outside passes through the color layer and is reflected by the reflective layer, wherein the pattern is disposed to be overlapped with the first area and the second area when viewed in a plan view, the pattern including a first pattern (PTa) and a second pattern (PTb), the cover unit further comprises a cover layer attached to the second pattern (PTb) disposed to be overlapped with the second area, and the cover layer is configured to prevent a diffusive reflection by the second pattern (PTb) disposed to be overlapped with the second area. a first base member disposable on a display device; a color layer on the first base member, the color layer implementing a color of the cover unit; a reflective layer; a pattern layer including a pattern on one surface of the pattern layer that makes contact with the reflective layer, the pattern layer being disposed on the color layer and the reflective layer being disposed on the pattern layer, the reflective layer having an intrinsic color determined by a material forming the reflective layer, wherein the first base member comprises a first area and a second area defined therein when viewed in a plan view, and each of the reflective layer and the color layer is overlapped with the first area and not overlapped with the second area when viewed in a plan view, wherein the reflective layer has a second color, and the color layer has a third color, the first area has a first color when viewed in a plan view by optically combining the second color of the reflective layer and the third color of the color layer, and the cover unit is configured such that a light incident from the outside passes through the color layer and is reflected by the reflective layer, wherein the pattern is disposed to be overlapped with the first area and the second area when viewed in a plan view, the pattern including a first pattern (PTa) and a second pattern (PTb), the cover unit further comprises a cover layer attached to the second pattern (PTb) disposed to be overlapped with the second area, and the cover layer is configured to prevent a diffusive reflection by the second pattern (PTb) disposed to be overlapped with the second area.
