wherein:
the first touch electrode comprises:
first touch patterns; and
a connection pattern connecting adjacent first touch patterns in the first direction;

the connection pattern has a minimum width in a direction perpendicular to a second direction, the second direction crossing the first direction;
the first direction and the absorption axis direction form a first directional angle equal to or less than substantially 90 degrees; and
the first direction and the second direction form a second directional angle equal to or less than substantially 90 degrees.

2. The display apparatus of claim 1 , wherein the second direction is parallel to the absorption axis direction.

3. The display apparatus of claim 1 , wherein each of the first directional angle and the second directional angle is substantially 45 degrees.

4. The display apparatus of claim 1 , wherein each of the first directional angle and the second directional angle in a counter-clock wise direction with respect to the first direction is more than substantially 0 degrees and equal to or less than substantially 90 degrees.

5. The display apparatus of claim 1 , wherein each of the first directional angle and the second directional angle in a clockwise direction with respect to the first direction is more than substantially 0 degrees and equal to or less than substantially 90 degrees.

6. The display apparatus of claim 1 , further comprising a second touch electrode disposed on the display panel, the second touch electrode extending in a third direction perpendicular to the first direction and electrically insulated from the first touch electrode,
wherein the second touch electrode comprises:
second touch patterns; and
a bridge pattern connecting adjacent second touch patterns in the third direction.

7. The display apparatus of claim 6 , further comprising a bending area,
wherein the display apparatus is configured to be bent in the bending area with respect to a reference axis substantially parallel to the third direction.

8. A display apparatus comprising:
a display panel configured to display an image;
a polarizing member disposed on the display panel and having an absorption axis and a transmission axis perpendicular to the absorption axis; and
a first touch electrode disposed on the display panel and overlapping the polarizing member, the first touch electrode extending in a first direction crossing an absorption axis direction, the absorption axis direction is parallel to the absorption axis,
wherein:
the first touch electrode comprises:
first touch patterns; and
a connection pattern connecting adjacent first touch patterns in the first direction;

the connection pattern has a minimum width in a direction perpendicular to a second direction, the second direction crossing the first direction;
the first direction and the absorption axis direction form a first directional angle equal to or less than substantially 90 degrees; and
the first direction and the second direction form a second directional angle equal to or less than substantially 90 degrees.

9. The display apparatus of claim 8 , wherein:
the second direction and the absorption axis direction form a third directional angle equal to or less than substantially 90 degrees; and
the second directional angle is the sum of the first directional angle and the third directional angle.

10. The display apparatus of claim 8 , wherein the second direction crosses the absorption axis direction.

11. The display apparatus of claim 8 , wherein:
the first directional angle in a counter-clock wise direction with respect to the first direction is more than substantially 0 degrees and equal to or less than substantially 90 degrees; and
the second directional angle in the counter-clock wise direction with respect to the first direction is more than substantially 0 degrees and equal to or less than substantially 90 degrees.

12. The display apparatus of claim 11 , wherein the second directional angle is more than substantially 45 degrees and the first directional angle is less than substantially 45 degrees.

13. The display apparatus of claim 8 , wherein:
the first directional angle in a clockwise direction with respect to the first direction is more than substantially 0 degrees and equal to or less than substantially 90 degrees; and
the second directional angle in the clockwise direction with respect to the first direction is more than substantially 0 degrees and equal to or less than substantially 90 degrees.

14. The display apparatus of claim 13 , wherein the second directional angle is more than substantially 45 degrees and the first directional angle is less than substantially 45 degrees.

15. A display apparatus comprising:
