Claims16
A window for a flexible display device, comprising:
- a first film including a base film and a plurality of unfilled holes passing through the base film;
- a second film overlapping the first film;
- a buffer layer between the first film and the second film to attach a first side of the first film and a first side of a second film, the buffer layer includes an elastic material for easing an impact by delaying a force transmission time when an external force is applied;
- and
- a hard coated layer on a second side of the second film,
- wherein the plurality of unfilled holes are formed in an entirety of the base film, and
- wherein a sum of volumes of the unfilled holes is equal to or greater than 5% and equal to or less than 50% of a volume of the first film, wherein the unfilled holes are configured to disperse the external force.
A flexible display device comprising:
- a display panel;
- a window on a first side of the display panel;
- and
- a first adhesive layer between the display panel and the window to attach the first side of the display panel and a first side of the window,
- wherein the window includes:
- a first film including a base film and a plurality of unfilled holes passing through the base film;
- a second film overlapping the first film;
- a buffer layer between the first film and the second film to attach a first side of the first film and a first side of a second film, the buffer layer includes an elastic material for easing an impact by delaying a force transmission time when an external force is applied;
- and
- a hard coated layer on a second side of the second film,
- wherein the plurality of unfilled holes are formed in the entirety of the base film,
- wherein a sum of volumes of the unfilled holes is equal to or greater than 5% and equal to or less than 50% of a volume of the first film, wherein the unfilled holes are configured to disperse the external force.
