Abstract

Disclosed is a display device. The display device includes first and second substrates, a plurality of gate lines and data lines, a connection line, a signal line, and a first bridge. The first and second substrates face each other. The gate lines and data lines are formed on the first substrate to define a plurality of pixels by an intersection therebetween. The connection line is formed on the first substrate to be electrically connected to the gate line. The signal line is formed on the second substrate for supplying a signal to the gate line. The first bridge is formed on the second substrate for electrically connecting the signal line and the connection line.

Claims (39)

1. A display device, comprising:

first and second substrates facing each other;

a plurality of gate lines and data lines on the first substrate to define a plurality of pixels by an intersection therebetween;

a connection line on the first substrate to be electrically connected to the gate line;

a signal line on the second substrate for supplying a signal to the gate line;

a first bridge on the second substrate for electrically connecting the signal line and the connection line;

a passivation layer comprising a first contact hole exposing the connection line;

a connection electrode connected to the connection line through the first contact hole; and

a black matrix comprising a second contact hole exposing the signal line.

2. The display device of claim 1 , wherein one end of the first bridge is connected to the signal line through the second contact hole, and the other end of the first bridge is protruded to contact with the connection electrode.

3. The display device of claim 1 , wherein the first bridge protrudes into the first contact hole.

4. The display device of claim 1 , wherein the first bridge protrudes to contact the connection electrode.

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

an adhesive member between the first bridge and the connection electrode.

6. The display device of claim 5 ,

wherein the adhesive member comprises a conductive ball.

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

a second bridge connected to the signal line, and

a gate pad connected to the second bridge.

8. The display device of claim 7 , further comprising:

a gate insulation layer exposing the gate pad; and

a pad electrode connected to the gate pad,

wherein the black matrix further exposes a part of the signal line, and

wherein the passivation layer further exposes the gate pad.

9. The display device of claim 8 ,

wherein the second bridge connects the signal line and the gate pad.

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

a gate pad on the second substrate, and wherein the gate pad and the signal line are electrically connected.

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

a data pad on the second substrate, and

a third bridge on the second substrate for electrically connecting the data pad and a data line.

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

a backlight unit disposed under the coupled substrate with the first and second substrate; and

a support member supporting the coupled substrate and the backlight unit,

wherein the support member comprises a set cover contacting a bottom of the coupled substrate.

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

a backlight unit disposed under the coupled substrate with the first and second substrate; and

a support member supporting the coupled substrate and the backlight unit,

wherein the support member comprises a set cover contacting a side surface of the coupled substrate.
