Abstract
A window includes: a window substrate including a bending portion bendable about a virtual bending axis that extends in a first direction; a plurality of groove patterns, which are defined in the bending portion, extend in the first direction, and are arranged in a second direction crossing the first direction; a sub groove, which is recessed into the window substrate from a pattern surface that define the plurality of at least one of groove patterns; and fillers, which fill the plurality of groove patterns and the sub groove. The sub groove includes a fixing region having a width that increases in a direction in which the sub groove is recessed.
Claims20
A window comprising:
- a window substrate comprising a bending portion bendable about a bending axis that extends in a first direction;
- a plurality of groove patterns recessed from a surface of the window substrate, which are defined in the bending portion, extend in the first direction, and are arranged in a second direction crossing the first direction;
- a sub groove, which is further recessed into the window substrate from a pattern surface that defines at least one of the plurality of groove patterns;
- and
- fillers, which fill the plurality of groove patterns and the sub groove,
- wherein the sub groove comprises:
- a fixing region having a width that increases in a direction in which the sub groove is further recessed such that in a cross-sectional view perpendicular to the first direction,
- a first sub groove portion adjacent to the pattern surface and having a constant width over a length in the direction in which the sub groove is further recessed;
- and
- a second sub groove portion extending from the first sub groove portion in the direction in which the sub groove is further recessed with a circular cross-section having a diameter exceeding the constant width, the second sub groove portion comprising the fixing region.
A display device operating in a first mode and a second mode in which the display surface is larger than in the first mode, the display device comprising:
- a display panel comprising a display bending portion bendable about a virtual bending axis that extends in the first direction;
- a window substrate, which is disposed on the display panel and comprises a bending portion corresponding to the display bending portion;
- a plurality of groove patterns recessed from a surface of the window substrate, which are defined in the bending portion, extend in the first direction, and are arranged in a second direction crossing the first direction;
- a sub groove, which is further recessed into the window substrate from a pattern surface that defines at least one of the plurality of groove patterns;
- and
- fillers, which fill the plurality of groove patterns and the sub groove,
- wherein the sub groove comprises:
- a fixing region having a width that increases in a direction in which the sub groove is further recessed such that in a cross-sectional view perpendicular to the first direction,
- a first sub groove portion adjacent to the pattern surface and having a constant width over a length in the direction in which the sub groove is further recessed;
- and
- a second sub groove portion extending from the first sub groove portion in the direction in which the sub groove is further recessed with a circular cross-section having a diameter exceeding the constant width, the second sub groove portion comprising the fixing region.
A window comprising:
- a window substrate comprising a bending portion bendable about a bending axis that extends in a first direction;
- a plurality of groove patterns recessed from a surface of the window substrate, which are defined in the bending portion, extend in the first direction, and are arranged in a second direction crossing the first direction;
- a sub groove, which is further recessed into the window substrate from a pattern surface that defines at least one of the plurality of groove patterns;
- and
- fillers, which fill the plurality of groove patterns and the sub groove,
- wherein, in a cross-sectional view perpendicular to the first direction, the sub groove has an anchor shape with a first sub groove portion adjacent the pattern surface and having a uniform width over a length and a distal end connected to a second sub groove portion having a circular shape with a diameter exceeding the uniform width such that the fillers are fixed to the sub groove.
