The window panel includes a window glass, decoration printed layers disposed on the window glass in the first and second non-display areas, and a light-blocking printed layer disposed on the window glass and the decoration printed layers to cover the decoration printed layers in the first non-display area and having a black color. A boundary line corresponding to a boundary between the display area and the non-display area is an inner surface of the light-blocking printed layer and the display area corresponds to the pixel area at the boundary line. ## Claims ### Claim 1 A display device, comprising: a window panel that includes a display area and a non-display area including a first non-display area surrounding the display area and a second non-display area surrounding the first non-display area; and a display panel that includes a pixel area generating an image to be displayed in the display area and a non-pixel area surrounding the pixel area, the window panel comprising: a window glass; a plurality of decoration printed layers disposed on the window glass in a portion of the first non-display area and an entire of the second non-display area; and a light-blocking printed layer having a black color, disposed on the window glass and the decoration printed layers, and covering the decoration printed layers in the first non-display area, a boundary line corresponding to a boundary between the display area and the non-display area being an inner surface of the light-blocking printed layer, and the display area geometrically corresponding to the pixel area along the boundary line. ### Claim 2 (depends on 1) The display device of claim 1, wherein the decoration printed layers comprise: a first decoration printed layer disposed on the window glass; a second decoration printed layer disposed on the first decoration printed layer; and a third decoration printed layer disposed on the second decoration printed layer, and the first decoration printed layer is spaced apart from the boundary line by a predetermined distance and disposed on the window glass in the portion of the first non-display area and the entire of the second non-display area. ### Claim 3 (depends on 2) The display device of claim 2, wherein a width of the first decoration printed layer is larger than a width of the second decoration printed layer, and the width of the second decoration printed layer is larger than a width of the third decoration printed layer. ### Claim 4 (depends on 3) The display device of claim 3, wherein the first decoration printed layer is disposed to be more adjacent to the display area than the second decoration printed layer, and the second decoration printed layer is disposed to be more adjacent to the display area than the third decoration printed layer. ### Claim 5 (depends on 4) The display device of claim 4, wherein the first, second, and third decoration printed layers have a same color except for the black color. ### Claim 6 (depends on 4) The display device of claim 4, wherein the first decoration printed layer comprises a pearl pigment that glitters and has a transparent color, and the second and third decoration printed layers have a color different from the color of the first decoration printed layer and have the same color except for the black color. ### Claim 7 (depends on 4) The display device of claim 4, wherein a distance between the boundary line and an inner surface of the first decoration printed layer is in a range from about 0.2 mm to about 0.5 mm. ### Claim 8 A method of manufacturing a display device, comprising: preparing a window glass including a display area and a non-display area, the non-display area including a first non-display area surrounding the display area and a second non-display area surrounding the first non-display area; forming a plurality of decoration printed layers on the window glass in a portion of the first non-display area and an entire of the second non-display area; forming a light-blocking printed layer, which has a black color, on the window glass and the decoration printed layers to cover the decoration printed layers in the first non-display area; disposing a display panel under the window glass, the display panel including a pixel area generating an image to be displayed in the display area and a non-display area surrounding the pixel area and the display panel being attached with an adhesive member; irradiating an exterior light onto the window glass and recognizing a boundary line that corresponds to an inner surface of the light-blocking printed layer and is defined as a boundary between the display area and the non-display area; arranging the pixel area to correspond to the display area along the boundary line; and attaching the display panel and the window glass to each other using the adhesive member. ### Claim 9 (depends on 8) The method of claim 8, wherein the forming of the decoration printed layers comprises: forming a first decoration printed layer on the window glass; forming a second decoration printed layer on the first decoration printed layer; and forming a third decoration printed layer on the second decoration printed layer, and the first decoration printed layer is spaced apart from the boundary line by a predetermined distance and formed on the window glass in the portion of the first non-display area and the entire of the second non-display area. ### Claim 10 (depends on 9) The method of claim 9, wherein a width of the first decoration printed layer is larger than a left-right width of the second decoration printed layer, the width of the second decoration printed layer is larger than a width of the third decoration printed layer, the first decoration printed layer is disposed to be more adjacent to the display area than the second decoration printed layer, and the second decoration printed layer is disposed to be more adjacent to the display area than the third decoration printed layer. ### Claim 11 (depends on 10) The method of claim 10, wherein the first, second, and third decoration printed layers have a same color except for the black color. ### Claim 12 (depends on 10) The method of claim 10, wherein the first decoration printed layer comprises a pearl pigment that glitters and has a transparent color, and the second and third decoration printed layers have a color different from the color of the first decoration printed layer and have the same color except for the black color. ### Claim 13 (depends on 10) The method of claim 10, wherein a distance between the boundary line and an inner surface of the first decoration printed layer is within a range from about 0.2 mm to about 0.5 mm.
