Abstract

A display device includes a display panel, and a pattern glass disposed on the display panel and including a first non-pattern portion, a pattern portion, and a second non-pattern portion, which are arranged in a first direction. The pattern portion includes a plurality of patterns having a shape and arranged in the first direction and a second direction intersecting the first direction, and openings defined through the pattern glass between the plurality of patterns adjacent to each other. Each of the openings has a symmetrical shape with respect to a third direction intersecting a plane defined by the first and second directions based on a symmetry axis extending in the second direction. The symmetry axis passes through a midpoint of a thickness of the pattern glass.

First claim

What is claimed is:

1 . A display device, comprising:
a display panel; and a pattern glass disposed on the display panel and comprising a first non-pattern portion, a pattern portion, and a second non-pattern portion, which are arranged in a first direction, wherein the pattern glass is disposed on a front surface of the display panel defining a display surface, wherein the pattern portion comprises:
a plurality of patterns having a shape and arranged in the first direction and a second direction intersecting the first direction; and
openings defined through the pattern glass between the plurality of patterns adjacent to each other,
each of the openings has a symmetrical shape with respect to a third direction intersecting a plane defined by the first and second directions based on a symmetry axis extending in the second direction, and the symmetry axis passes through a midpoint of a thickness of the pattern glass.

2 . The display device of claim 1 , wherein the openings have a shape corresponding to the plurality of patterns in a plan view.

3 . The display device of claim 2 , wherein
the plurality of patterns are repeatedly arranged, and are not separated from each other, and each of the plurality of patterns has a same shape.

4 . The display device of claim 3 , wherein the shape of each of the plurality of patterns has at least one of a cross-like shape, a snow crystal shape, a scale shape, a pinwheel shape, a spiral shape, an octagonal shape, or a column shape.

5 . The display device of claim 4 , wherein
the openings have a straight line shape alternately extending in the first direction and the second direction in the plan view, and each of the openings has a width within a range of about 5 micrometers to about 10 micrometers.

6 . The display device of claim 3 , wherein
the shape of each of the plurality of patterns has a spiral shape in the plan view, and the openings have a curved shape in the plan view.

7 . The display device of claim 2 , wherein
the plurality of patterns have wave patterns arranged in a plurality of rows, and the plurality of rows correspond to the second direction.

8 . The display device of claim 7 , wherein
each of the wave patterns have a length within a range of about 0.625 mm to about 1.125 mm in the second direction, and lengths in the second direction of the wave patterns are different from each other.

9 . The display device of claim 7 , wherein
a distance between the wave patterns adjacent to each other in the second direction is within a range of about 10 micrometers to about 200 micrometers, and distances between the wave patterns adjacent to each other are different from each other.

10 . The display device of claim 9 , wherein the wave patterns adjacent to each other in the second direction have different wavelengths from each other.

11 . The display device of claim 9 , wherein at least one wave pattern among the wave patterns has a uniform wavelength.

12 . The display device of claim 9 , wherein wavelengths of the wave patterns vary.

13 . The display device of claim 1 , wherein
inner side surfaces of the pattern portion are defined by surfaces of the plurality of patterns facing each other to define the openings, and the inner side surfaces of the pattern portion have a straight line shape extending in the third direction when viewed in the first direction.

14 . The display device of claim 1 , wherein
inner side surfaces of the pattern portion are defined by surfaces of the plurality of patterns facing each other to define the openings, and the inner side surfaces of the pattern portion have a convex shape toward the openings when viewed in the first direction.

15 . The display device of claim 14 , wherein the pattern portion further comprises:
first slant surfaces connecting the inner side surfaces of the pattern portion and an upper surface of the pattern portion when viewed in the first direction; and second slant surfaces connecting the inner side surfaces of the pattern portion and a lower surface of the pattern portion when viewed in the first direction.

16 . The display device of claim 1 , wherein the openings have a tapered shape in which a width of the openings increases from a midpoint of a thickness of the pattern portion to an upper surface or a lower surface of the pattern portion when viewed in the first direction.

17 . A display device, comprising:
a display panel; and a pattern glass disposed on the display panel and comprising a first non-pattern portion, a pattern portion, and a second non-pattern portion, which are arranged in a first direction, wherein the pattern portion comprises:
a plurality of patterns having a shape, arranged in the first direction and a second direction intersecting the first direction in a plan view, and having a wave pattern; and
openings defined through the pattern glass between the plurality of patterns adjacent to each other in the second direction, and
the plurality of patterns which have the wave pattern have different amplitudes from each other in a plan view.

18 . The display device of claim 17 , wherein each of the openings has a symmetrical shape with respect to a third direction intersecting a plane defined by the first and second directions based on a symmetry axis extending in the second direction.

19 . The display device of claim 17 , wherein at least one pattern of the plurality of patterns has a uniform wavelength and extends in the first direction.

20 . The display device of claim 17 , wherein a first amplitude value varies from a second amplitude value in each of the plurality of patterns.

21 . An electronic device comprising a display device for providing an image,
wherein the display device comprises: a display panel; and a pattern glass disposed on the display panel and comprising a first non-pattern portion, a pattern portion, and a second non-pattern portion, which are arranged in a first direction, wherein the pattern glass is disposed on a front surface of the display panel defining a display surface, wherein the pattern portion comprises:
a plurality of patterns having a shape and arranged in the first direction and a second direction intersecting the first direction; and
openings defined through the pattern glass between the plurality of patterns adjacent to each other,
each of the openings has a symmetrical shape with respect to a third direction intersecting a plane defined by the first and second directions based on a symmetry axis extending in the second direction, and the symmetry axis passes through a midpoint of a thickness of the pattern glass.
