3. The supporting member for the display device of claim 2 , wherein
a space between two patterns of the plurality of patterns adjacent in the second direction is adjacent to a center of a pattern of the plurality of patterns adjacent in the first direction.
4. The supporting member for the display device of claim 1 , wherein
each of the plurality of patterns is a groove or hole.
5. The supporting member for the display device of claim 4 , wherein
each of the plurality of patterns has a shape such that a width thereof in the first direction gradually becomes narrower toward a bottom thereof on a cross-section.
6. A display device comprising:
a display panel which displays an image;
a digitizer which detects a touch; and
a supporting member positioned between the display panel and the digitizer and made of a non-metal material,
wherein the supporting member includes a first region and a second region, and a third region positioned between the first region and the second region,
the supporting member includes a plurality of patterns positioned in the third region and adjacent to one another in a first direction and a second direction perpendicular to the first direction, and
each of the plurality of patterns extends along the second direction,
wherein the supporting member is formed of or includes an aramid fiber reinforced plastic.
7. The display device of claim 6 , wherein
the third region is foldable with respect to a folding axis extended in the second direction,
each of the plurality of patterns has a length greater than a width in a plan view, and
the length is measured in the second direction, and the width is measured in the first direction.
8. The display device of claim 7 , wherein
a space between two patterns of the plurality of patterns adjacent in the second direction is adjacent to a center of a pattern of the plurality of patterns adjacent in the first direction.
9. The display device of claim 6 , wherein
each of the plurality of patterns is a groove or hole.
10. The display device of claim 9 , wherein
each of the plurality of patterns has a shape such that a width thereof in the first direction gradually becomes narrower toward a bottom thereof on a cross-section.
11. The display device of claim 6 , wherein
the digitizer includes a first digitizer overlapping the first region of the supporting member and a second digitizer overlapping the second region of the supporting member, and
the first digitizer and the second digitizer are separated from each other.
12. The display device of claim 6 , further comprising
a metal plate positioned under the digitizer,
wherein the metal plate includes a first metal plate overlapping the first region of the supporting member and a second metal plate overlapping the second region of the supporting member, and
the first metal plate and the second metal plate are separated from each other.
13. A manufacturing method of a supporting member for a display device, comprising:
preparing a precursory supporting member made of a non-metal material;
attaching a dry film on the precursory supporting member;
patterning the dry film;
processing the precursory supporting member by using the patterned dry film as a mask through a micro blast process to form a plurality of patterns on the precursory supporting member, wherein the precursory supporting member becomes a supporting member after the processing; and
removing the patterned dry film.
14. The manufacturing method of the supporting member for the display device of claim 13 , wherein
the supporting member includes a first region and a second region, and a third region disposed between the first region and the second region,
a plurality of patterns are disposed in the third region and adjacent to one another in the first direction and the second direction perpendicular to the first direction, and
each of the plurality of patterns extends along the second direction.
15. The manufacturing method of the supporting member for the display device of claim 14 , wherein
the third region is foldable with respect to a folding axis extended in the second direction,
each of the plurality of patterns has a length greater than a width in a plan view, and
the length is measured in the second direction, and the width is measured in the first direction.
16. The manufacturing method of the supporting member for the display device of claim 15 , wherein
a space between two patterns of the plurality of patterns adjacent in the second direction is adjacent to a center of a pattern of the plurality of patterns adjacent in the first direction.
17. The manufacturing method of the supporting member for the display device of claim 13 , wherein
each of the plurality of patterns is a groove or hole.
18. The manufacturing method of the supporting member for the display device of claim 17 , wherein
each of the plurality of patterns has a shape such that a width thereof in the first direction gradually becomes narrower toward a bottom thereof on a cross-section.
19. The manufacturing method of the supporting member for the display device of claim 13 , wherein
the supporting member for the display device is formed of or include at least one of a carbon fiber reinforced plastic, a glass fiber reinforced plastic, and an aramid fiber reinforced plastic.
20. The manufacturing method of the supporting member for the display device of claim 13 , wherein
