Abstract
A method of manufacturing a window may include cutting a window having a uniform thickness of about 20 μm to about 100 μm and polishing a cut surface of the window with a polishing pad having an elastic modulus less than an elastic modulus of the window while applying slurry to the cut surface of the window.
Claims13
A flexible display device, comprising:
- a bendable glass window having a thickness within a range of 20 μm to 100 μm in a first direction, the glass window having a flat portion and an edge of the glass window having a curved cross-sectional shape,
- wherein an image is displayed through the glass window, and
- wherein the curved cross-sectional shape of the glass window has a radius of curvature at a location farthest from the flat portion that is less than a distance from the location farthest from the flat portion to the flat portion and angle with respect to a plane of the flat portion to a point on an imaginary circle of the radius of curvature is 10 degrees to 30 degrees.
A method of manufacturing a glass window for a display device, the method comprising:
- stacking glass windows in a first direction, the glass windows each having a thickness within a range of about 20 μm to about 100 μm in the first direction;
- and
- polishing edges of the glass windows in a mechanical manner,
- wherein each of the glass windows has a flat portion and an edge having a curved cross-sectional shape having a radius of curvature at a location farthest from the flat portion that is less than a distance from the location farthest from the flat portion to the flat portion and an angle with respect to a plane of the flat portion to a point on an imaginary circle of the radius of curvature is 10 degrees to 30 degrees.
