A cutting part is formed in the display substrate and the connector, and the cutting part is formed adjacent to the dummy pattern.

Claims

1. An electronic device comprising:

a display substrate including a screen area and a peripheral area in which a first conductive pattern is formed, the peripheral area surrounding at least a portion of the screen area;

a connector on which a second conductive pattern is formed, the connector including a curved portion;

a conductive bonding layer disposed between the peripheral area of the display substrate and the connector, and electrically connecting the first conductive pattern and the second conductive pattern; and

a cutting part disposed through the display substrate, the conductive bonding layer, and the connector,

wherein the cutting part includes a first portion surrounded by the peripheral area of the display substrate, and a second portion surrounded by the curved portion of the connector.

2. The electronic device of claim 1, wherein the conductive bonding layer comprises an anisotropic conductive film.

3. The electronic device of claim 1, wherein the connector comprises a flexible printed circuit board.

4. The electronic device of claim 1, wherein the cutting part further includes a first cutting part formed on one side of the display substrate and a second cutting part formed on one side of the connector, and wherein the connector further includes a dummy pattern.

5. The electronic device of claim 4, wherein the connector is bent to surround a periphery of one side of the display substrate, and at least a portion of the first cutting part and at least a portion of the second cutting part are aligned according to a cutting direction thereof.

6. The electronic device of claim 4, wherein the dummy pattern is separated from a periphery of the second cutting part by a spacing gap and has a width.

7. The electronic device of claim 4, wherein the connector comprises a first connector and a second connector, wherein the second connector has a property different from that of the first connector.

8. The electronic device of claim 7, wherein the first connector comprises a flexible printed circuit board, the second connector is connected to one side of the first connector, and the second connector and the display substrate are bonded to each other by the conductive bonding layer.

9. The electronic device of claim 8, wherein the second connector has an electrode part that has an electrode pattern and a non-electrode part that does not have an electrode pattern, and the second cutting part is formed in the non-electrode part of the second connector.

10. The electronic device of claim 9, wherein the dummy pattern is formed at an outer side of the second cutting part, and the dummy pattern extends along at least a portion of the second cutting part.

11. The electronic device of claim 10, wherein the dummy pattern is separated from a periphery of the second cutting part by a spacing gap and has a width.

12. An electronic device comprising:

a display substrate;

a connector connected to one side of the display substrate; and

an opening extending from a portion of the display substrate to a portion of the connector,

wherein the connector includes a dummy pattern extending along a periphery of the opening, and a via hole formed between the dummy pattern and the opening,

wherein at least a portion of the via hole is connected to the opening, and

wherein the connector is bent such that a portion of the opening formed in the connector and the display substrate is aligned with a remaining portion of the opening formed in the connector.

13. An electronic device comprising:

a housing comprising a first plate facing a first direction and a second plate facing a second direction opposite to the first direction;

a display disposed within the housing and exposed through the first plate; and

a component disposed adjacent to the display, when viewed from the top of the first plate,

wherein the display comprises;

a display substrate having;

a first surface disposed in parallel to the first plate and facing the first direction, a second surface facing the second direction, and a third surface facing a third direction that is substantially perpendicular to the first surface; and

a connector having;

a first part disposed on the first surface, a second part disposed on the second surface, and a third part extending from the first part to the second part and covering at least a portion of the third surface,

wherein a peripheral portion of the display substrate comprises a recess,

wherein portions of the first part, the second part, and the third part of the connector are cut along the recess of the display substrate, when viewed from above the first plate,

wherein the connector comprises;
