Display device and method for fabricating the same

A display device comprising:

• a window;
• and
• a display panel coupled to a bottom surface of the window and having:
• a display area having a substantially regular tetragonal shape or a substantially rectangular shape in a plan view;
• and
• a non-display area outside of the display area, wherein the window comprises:
• a base member;
• and
• a bezel layer on a bottom surface of the base member, between one and three light-transmissive main alignment marks and a transmission area having a different shape than that of the display area being defined in the bezel layer, and
• wherein each of the main alignment marks is arranged at a position corresponding to a vertex of an imaginary regular tetragon or an imaginary rectangle that has the same center point as the display area and is larger than the display area.

A display device comprising:

• a window;
• and
• a display panel coupled to a bottom surface of the window and having a regular tetragonal shape with a curved corner area in a plan view or a rectangular shape with a curved corner area in a plan view,
• wherein the window comprises:
• a base member;
• and
• a bezel layer on a bottom surface of the base member, between one and three light-transmissive main alignment marks and a transmission area having a different shape than that of the display panel being defined in the bezel layer,
• wherein each of the main alignment marks is arranged at a position corresponding to a vertex of the display panel or at a position corresponding to a vertex of an imaginary regular tetragon or an imaginary rectangle that has the same center point as the display panel and that is larger than the display panel.

A display device comprising:

• a window;
• and
• a display panel coupled to a bottom surface of the window and having a substantially regular polygonal shape having n edges in a plan view,
• wherein the window comprises:
• a base member;
• and
• a bezel layer on a bottom surface of the base member, a number of light-transmissive alignment marks and a transmission area having a different shape than that of the display panel being defined in the bezel layer,
• wherein the number of the alignment marks is n-i, where “i” is a natural number equal to or greater than one and less than “n”, and
• wherein each of the alignment marks is arranged at a position corresponding to a vertex of the display panel or at a position corresponding to a vertex of an imaginary polygon that has the same center point as the display panel and that is larger than the display panel.

A method for fabricating a display device, the method comprising:

• preliminarily aligning a display panel with a window, the display panel having a substantially regular tetragonal shape or a substantially rectangular shape, the window having a transmission area having a different shape than that of the display panel, a non-transmission area adjacent to the transmission area, and a number of main alignment marks in the non-transmission area;
• calculating positions of vertices of the display panel and a position of a center point of the display panel;
• calculating positions of imaginary points on the window corresponding to at least some of the vertexes of the display panel and a position of an alignment center point of the window corresponding to the center point of the display panel by using numerical information of the display panel and the main alignment marks;
• aligning the center point of the display panel with the alignment center point of the window such that the center point coincides with the alignment center point;
• and
• coupling the window and the display panel to each other,
• wherein the number of the main alignment marks is less than the number of the vertices of the display panel.
