Abstract

A method of manufacturing a display device includes providing a window including a printed area and a plurality of alignment key areas, patterning a printed layer on the printed area such that the plurality of alignment key areas is exposed and the printed layer covers the printed area, aligning a panel to the window by using the plurality of alignment key areas, and coupling the panel to the window.

First claim

What is claimed is:

1. A display device comprising:
a window comprising a printed area and a plurality of alignment key areas spaced apart from each other;
a printed layer configured to cover the printed area and to expose the plurality of alignment key areas; and
a touch panel comprising a plurality of first alignment marks spaced apart from each other,
wherein an alignment center point, defined by an intersection of imaginary lines which connect positions of alignment keys in the plurality of alignment key areas, and a first center point, defined by imaginary lines which connect first positions of the plurality of first alignment marks, are overlapped.

2. The display device of claim 1 , further comprising:
a display panel comprising a plurality of second alignment marks spaced from each other,
wherein the alignment center point and a second center point, defined by an intersection of imaginary lines connecting second positions of the plurality of second alignment marks, are overlapped.

3. The display device of claim 1 ,
wherein the window comprises a display part on which images are displayed and a non-display part configured to block images,
wherein the non-display part has the plurality of alignment key areas and the printed areas, and
wherein a shape of the display part when viewed in a plane is substantially circular or elliptical.

4. The display device of claim 3 ,
wherein the display part is symmetrical with respect to an imaginary X-axis parallel to a first direction and is symmetrical with respect to an imaginary Y-axis parallel to a second direction perpendicular to the first direction, and a center point of the display part is an intersection of the X-axis and Y-axis.

5. The display device of claim 1 ,
wherein the printed layer is on the printed area and comprises a printing material.

6. The display device of claim 5 ,
wherein the printing material comprises a printed film.
