DISPLAY DEVICE

1 . A display device, comprising:

a flexible substrate;

a display layer disposed on the flexible substrate and including a plurality of light emitting units; and

a plurality of bending sensor units disposed on the display layer;

wherein at least one of the plurality of bending sensor units is disposed between and does not overlap at least two adjacent light emitting units of the plurality of light emitting units in a top view of the display device.

2 . The display device as claimed in claim 1 , wherein a density of the plurality of bending sensor units is less than a density of the plurality of light emitting units.

3 . The display device as claimed in claim 1 , further comprising:

a first conductive line disposed on the display layer and extending along a first direction; and

a second conductive line disposed on the first conductive line and extending along a second direction different from the first direction, wherein the second conductive line intersects the first conductive line to form the at least one of the plurality of bending sensor units.

4 . The display device as claimed in claim 3 , wherein the second conductive line has a first width and a second width along the first direction, and the first width is different from the second width.

5 . The display device as claimed in claim 4 , wherein the first width corresponds to the at least one of the bending sensor unit, and the first width is greater than the second width.

6 . The display device as claimed in claim 3 , further comprising:

an insulating layer disposed between the first conductive line and the second conductive line in a vertical direction perpendicular to a surface of the flexible substrate.

7 . The display device as claimed in claim 6 , wherein the insulating layer includes an organic material.

8 . The display device as claimed in claim 7 , wherein the insulating layer has a Young's Modulus in a range from 0.01 GPa to 10 GPa.

9 . The display device as claimed in claim 3 , wherein at least one of the first conductive line and the second conductive line comprises a plurality of openings.

10 . The display device as claimed in claim 9 , wherein the first conductive line includes a plurality of first openings, the second conductive line includes a plurality of second openings, and the first openings and the second openings overlap to form a plurality of overlapping openings.

11 . The display device as claimed in claim 10 , wherein in the top view, some of the plurality of light emitting units are disposed in positions corresponding to the plurality of overlapping openings.

12 . The display device as claimed in claim 1 , further comprising:

a conductive line CL disposed on the display layer and extending along a second direction, wherein the display device is bendable along the second direction.
