Abstract

Disclosed is a display device. The display device includes an upper substrate; a lower substrate having gate and data lines, with exposing a part of the lower surface of the upper substrate; a sealant for adhering the upper substrate to the lower substrate; a panel driver connected to the part of a lower surface of the upper substrate; a pad formed on the lower substrate, for applying a signal to the gate and data lines; and a connection part formed on the upper substrate, for connecting the pad and the panel driver. Accordingly, the thickness of the display device decreases, and a step height is not formed at a front surface of the display device, whereby the present invention can obtain an aesthetic design effect in that the front surface of the display device is shown as one structure.

Claims (35)

1. A display device comprising:

a lower substrate having gate and data lines;

an upper substrate formed as a color filter substrate with color filters, wherein the upper substrate extends longer than the lower substrate;

a sealant for adhering the upper substrate to the lower substrate;

a panel driver connected to a bottom of the longer-extending upper substrate;

a pad formed on the lower substrate, for applying a signal to the gate and data lines; and

a connection part formed on the upper substrate, for connecting the pad and the panel driver,

wherein the connection part comprises:

a pad contact part contacting the pad;

a driver contact part contacting the panel driver;

a connection line connecting the pad contact part and the driver contact part; and

a protrusion portion formed between the upper substrate and the pad contact part and guiding the pad contact part to be connected to the pad.

2. The display device of claim 1 , further comprising a contact assistance mean formed between the pad and the pad contact part.

3. The display device of claim 2 , wherein the contact assistance mean comprises a conductive ball.

4. The display device of claim 3 , wherein the contact assistance mean comprises the conductive ball formed in a valley area of the pad.

5. The display device of claim 1 , further comprising a light blocking layer formed between the upper substrate and the connection part.

6. The display device of claim 1 , further comprising a light blocking layer formed at a upper surface of the upper substrate corresponding to the connection part.

7. The display device of claim 1 , further comprising a conductive line connected to the connection part for reducing a resistance of the connection part.

8. The display device of claim 7 , wherein the conductive line is formed at a lower surface of the upper substrate, and covered by the connection part.

9. The display device of claim 7 , wherein the conductive line is stacked to the connection part.

10. The display device of claim 9 , wherein the conductive line is formed between the connection line and the lower surface of the upper substrate.

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

a light blocking layer cover the conductive line with a contact hole exposing a part of the conductive line.

12. The display device of claim 11 , wherein the connection part is connected to the conductive line through the contact hole.

13. The display device of claim 1 , further comprising an auxiliary display device formed on the upper substrate.

14. The display device of claim 13 , wherein the auxiliary display device is formed on a part of a lower surface of the upper substrate or a front surface of the upper substrate corresponding to the part of the lower surface of the upper substrate.

15. The display device of claim 1 , wherein the sealant is formed more outward than the pad.

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

a backlight unit disposed under the display panel; and

a support member supporting the display panel and the backlight unit,

wherein the support member comprises a set cover contacting a side surface of the display panel.

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

a backlight unit disposed under the display panel; and

a support member supporting the display panel and the backlight unit,

wherein the support member comprises a set cover contacting a bottom of the display panel.
