Abstract

A liquid crystal display panel includes first and second substrates attached to each other by a seal pattern, the seal pattern being outside of a display region, a liquid crystal layer between the first and second substrates in the display region, a silver dot outside the seal pattern for electrically connecting the first substrate to the second substrate, and a first line-on-glass line and a second line-on-glass line on the first substrate outside the display region, the first line-on-glass line is completely in a pad region outside of the silver dot.

Claims (33)

1. A liquid crystal display panel, comprising:

first and second substrates attached to each other by a seal pattern, the seal pattern being outside of a display region;

a plurality of data and gate lines in a matrix-like manner, thereby defining a plurality of pixels at the display region;

a data driving circuit for driving the data lines;

a gate driving circuit for driving the gate lines,

a liquid crystal layer between the first and second substrates in the display region;

a silver dot outside the seal pattern for electrically connecting the first substrate to the second substrate; and

a first line-on-glass line and a second line-on-glass line for connecting the data driving circuit to the gate driving circuit for applying a signal to the gate driving circuit, the first line-on glass line and the second line-on-glass line being disposed on the first substrate outside the display region,

wherein the first line-on-glass line is completely in a pad region outside of the silver dot and the second line-on-glass line being disposed on the pad region between the silver dot and the seal pattern.

2. The liquid crystal display panel according to claim 1 , wherein the second line-on-glass line has a first portion between the silver dot and the display region.

3. The liquid crystal display panel according to claim 2 , wherein the first portion is between the silver dot and the seal pattern.

4. The liquid crystal display panel according to claim 1 , wherein the second line-on-glass line has a portion overlapping the seal pattern.

5. The liquid crystal display panel according to claim 4 , wherein the second line-on-glass line includes a plurality holes where the second line-on-glass line overlaps the seal pattern.

6. The liquid crystal display panel according to claim 1 , wherein scan signals are applied to the first line-on-glass line.

7. The liquid crystal display panel according to claim 1 , further comprising a third line-on-glass line being parallel to the first line-on-glass line.

8. The liquid crystal display panel according to claim 7 , wherein a common voltage is applied to the first line-on-glass line, and a ground voltage is applied to the third line-on-glass line.

9. The liquid crystal display panel according to claim 7 , wherein a common voltage is supplied to the line-on-glass line closest to the silver dot among the first line-on-glass line and the third line-on-glass line.

10. The liquid crystal display panel according to claim 1 , wherein a common voltage is applied from the first substrate to the second substrate through the silver dot.

11. A liquid crystal display device, comprising:

a first substrate including a first region, a second region, a third region and a fourth region, the second region being at a periphery of the first region, the third region being at a periphery of the second region, and the fourth region being at a periphery of the third region;

a plurality of data and gate lines in a matrix-like manner, thereby defining a plurality of pixels at the first region;

a data driving circuit for driving the data lines;
