Abstract

An electronic panel including a base layer having a sensing area and a peripheral area adjacent to the sensing area, sensing electrodes overlapping the sensing area and disposed on the base layer, first lines overlapping the peripheral area and connected to one end and the other end of each of the sensing electrodes, an insulation layer including a first insulation portion configured to cover the sensing electrodes and disposed on the base layer and a second insulation portion configured to cover at least a portion of each of the first lines and disposed on the base layer, and second lines disposed on the second insulation portion and respectively electrically connected to the first lines through contact holes defined in the second insulation portion. The at least a portion of each of the first lines has a meandering shape.

Claims (36)

1. An electronic panel comprising:

a base layer including a sensing area and a peripheral area adjacent to the sensing area;

sensing electrodes overlapping the sensing area and disposed on the base layer;

first lines overlapping the peripheral area and connected to the sensing electrodes;

an insulation layer comprising a first insulation portion configured to cover the sensing electrodes and disposed on the base layer and a second insulation portion configured to cover at least a portion of each of the first lines and disposed on the base layer; and

second lines disposed on the second insulation portion and respectively electrically connected to the first lines through contact holes defined in the second insulation portion,

wherein:

the first lines comprise:

first sub-lines, each of which is connected to one end of each of the sensing electrodes;

second sub-lines connected to other ends of the sensing electrodes, respectively; and

connection lines respectively connected to the second lines through the contact holes and configured to connect the first sub-lines to the second sub-lines; and

each of the connection lines has the meandering shape.

2. The electronic panel of claim 1 , wherein the at least a portion of each of the first lines comprises:

a first portion extending in a first direction;

a second portion extending in the first direction to face the first portion in a second direction different from the first direction; and

a third portion extending in the second direction to connect the first portion to the second portion.

3. The electronic panel of claim 1 , wherein the at least a portion of each of the first lines has a curved shape.

4. The electronic panel of claim 1 , wherein the connection lines are entirely covered by the second insulation portion.

5. The electronic panel of claim 1 , wherein one second sub line of the second sub-lines crosses two or more second lines of the second lines on a plane.

6. The electronic panel of claim 1 , wherein each of the first sub-lines has the meandering shape.

7. The electronic panel of claim 6 , wherein the first sub-lines do not overlap the insulation layer.

8. The electronic panel of claim 1 , wherein the first sub-lines, the second sub-lines, and the connection lines are disposed on the base layer through the same process.

9. The electronic panel of claim 1 , wherein:

the second lines extend in a first direction and are spaced a predetermined distance from each other in a second direction different from the first direction; and

each of the second lines has a planar area per unit length greater than that of each of the first lines.

10. The electronic panel of claim 9 , wherein:

each of the second lines comprises a first line portion bonded to an external circuit board and a second line portion that overlaps the at least a portion of each of the first lines; and

the at least the portion of each of the first lines is disposed between the contact holes and the first line portion in the first direction.

11. The electronic panel of claim 10 , wherein the contact holes are disposed in the same line in the second direction.

12. The electronic panel of claim 11 , wherein the second lines have the same length in the first direction.

13. The electronic panel of claim 10 , wherein:

at least two second lines of the second lines have different lengths in the first direction; and

the contact holes overlapping the two second lines among the contact holes are defined in different lines in the second direction.

14. The electronic panel of claim 1 , wherein the first insulation portion and the second insulation portion are spaced apart from each other on a plane.

15. The electronic panel of claim 1 , wherein each of the first lines comprises a metal, and

each of the second lines comprises an ITO electrode.
