Abstract

A display device includes an input sensing unit. The input sensing unit includes sensors and signal lines connecting the sensors to a driving circuit for sensing a touch. The signal lines may include reception signal lines and transmission signal lines. A resistance value of the reception signal line connected to the sensor relatively far from the driving circuit is smaller than a resistance value of the reception signal line connected to the sensor relatively close to the driving circuit.

Claims (22)

1. A display device comprising:

a display panel including a first region and a second region spaced apart from the first region in a first direction, and including a light-emitting element layer disposed in the first region and an encapsulation layer sealing the light-emitting element layer;

a driving circuit disposed on the second region and providing an electrical signal for controlling the light-emitting element layer;

sensors disposed on the display panel and overlapping the first region; and

lines disposed on the display panel and electrically connected to the sensors, respectively, and extending from the sensors toward the second region, wherein,

the lines comprise first lines and second lines,

the first lines and the second lines are spaced apart from each other in a second direction crossing the first direction with the driving circuit interposed therebetween,

the first lines and the second lines are symmetrical with respect to the driving circuit,

a first line of the first lines closest to the second lines has a first bent portion bent in the second direction toward the second lines and a first extended portion extending along the first direction,

a second line of the second lines closest to the first lines has a second bent portion bent in the second direction toward the first lines and a second extended portion extending along the first direction,

the first bent portion and the second bent portion are disposed between the driving circuit and the light-emitting layer, and

the first extended portion and the second extended portion spaced apart from each other with the driving circuit interposed therebetween.

2. The display device of claim 1 , wherein the sensors comprise first sensors arranged along the first direction, and second sensors arranged along the second direction,

wherein the lines further comprise third lines and fourth lines;

wherein the first lines are electrically connected to some second sensors of the second sensors, respectively,

wherein the second lines are electrically connected to remaining second sensors of the second sensors, respectively,

wherein the third lines are electrically connected to some first sensors of the first sensors, respectively, and

wherein the fourth lines are electrically connected to remaining first sensor of the first sensors, respectively.

3. The display device of claim 2 , wherein the some first sensors and the remaining first sensors are sequentially arranged along the first direction.

4. The display device of claim 2 , wherein a number of the some first sensors and a number of the remaining first sensors are same, and the number of the some second sensors and number of the remaining second sensors are same.

5. The display device of claim 1 , wherein the sensors have a mesh shape and the sensors are disposed directly on the encapsulation layer.

6. The display device of claim 1 , wherein a first distance between the first bent portion and the second bent portion is less than a second distance between the first extended portion and the second extended portion.
