Abstract

An input sensor including a first electrode and a second electrode, which cross each other. The first electrode includes a first main portion extending in a first direction and first sensing portions and second sensing portions, which are disposed with the first main portion therebetween in a second direction and each of which extends from the first main portion. Each of the first sensing portions and the second sensing portions includes first sub-portions extending in the first direction and first middle portions disposed between the first sub-portions and between one of the first sub-portions and the first main portion.

Claims (40)

1 . A display device comprising:

a display panel; and

an input sensor disposed on the display panel and comprising a first electrode extending in a first direction and a second electrode extending in a second direction crossing the first direction,

wherein the first electrode comprises:

a first main portion extending in the first direction; and

a first sensing portion and a second sensing portion, which are disposed with the first main portion therebetween in the second direction and each of which extends from the first main portion; and

each of the first sensing portion and the second sensing portion comprises:

a first-first sub portion extending in the first direction;

a first-second sub portion extending in the first direction;

a first-first middle portion disposed between the first-first sub portion and the first main portion; and

a first-second middle portion disposed between the first-second sub portion and the first-first sub portion,

wherein a length of each of the first-first sub portion and the first-second sub portion is greater than a length of each of the first-first middle portion and the first-second middle portion in the first direction,

wherein the second electrode comprises a third sensing portion and a fourth sensing portion, which are disposed with the first main portion therebetween in the second direction,

wherein each of the third sensing portion and the fourth sensing portion comprises:

a first portion;

a second portion facing the first portion in the first direction; and

a third portion disposed between the first portion and the second portion and extending in the first direction,

wherein each of the first portion and the second portion includes a first sub portion disposed between and overlapping the first-first sub portion and the first main portion in the second direction and a second sub portion disposed between and overlapping the first-second sub portion and the first-first sub portion of one of the first sensing portion or the second sensing portion in the second direction.

2 . The display device of claim 1 , wherein the second electrode further comprises a bridge disposed on a different layer from the third sensing portion and the fourth sensing portion and connecting the third sensing portion and the fourth sensing portion and overlapping the first main portion.

3 . The display device of claim 2 , wherein:

the display panel comprises a light emitting element and an upper insulation layer covering the light emitting element; and

the input sensor further comprises a sensor insulation layer contacting the bridge; and

one of the bridge and the sensor insulation layer contacts the upper insulation layer.

4 . The display device of claim 1 , wherein the first sensing portion includes a first-first sensing portion and a first-second sensing portion spaced apart from the first-first sensing portion in the second direction, and

the second sensing portion includes a second-first sensing portion and a second-second sensing portion spaced apart from the second-first sensing portion in the second direction.

5 . The display device of claim 4 , wherein the first portion of the third sensing portion is disposed between the first-first sensing portion and the first-second sensing portion in the first direction, and

the first portion of the fourth sensing portion is disposed between the second-first sensing portion and the second-second sensing portion in the first direction.

6 . The display device of claim 4 , wherein the second portion includes a second-first portion and a second-second portion, and

the first-first sensing portion is disposed between the second-first portion and the first portion in the first direction, and

the first-second sensing portion is disposed between the second-second portion and the first portion in the first direction.

7 . The display device of claim 1 , wherein the input sensor further comprises a dummy electrode disposed between the first sensing portion and the third sensing portion.

8 . The display device of claim 7 , wherein the dummy electrode is disposed between the first-second sub portion and the third portion.

9 . The display device of claim 1 , wherein:

the display panel comprises a plurality of light emitting areas; and

the first electrode and the second electrode comprise a plurality of conductive lines configured to define a plurality of openings corresponding to the plurality of light emitting areas.

10 . The display device of claim 1 , wherein the display device is foldable with respect to a reference axis.

11 . The display device of claim 1 , further comprising:

an upper member disposed on the input sensor and comprising a polarizer; and

an adhesive member attaching the upper member and the input sensor.

12 . The display device of claim 11 , wherein the first electrode and the second electrode contact the adhesive member.
