Abstract

A liquid crystal display panel includes a first substrate, an image display part formed on the first substrate and having a plurality of pixels arranged thereon, a plurality of gate and source drivers for supplying signals to the pixels, a controller for supplying control signals to the gate and source drivers, at least one conductive line at a corner portion of the first substrate, the conductive line connecting the controller and the gate drivers, and a plurality of transparent electrode segments overlapping the conductive line with at least one intermediate film interposed therebetween.

Claims (14)

1. A liquid crystal display panel, comprising:

a first substrate;

an image display part formed on the first substrate and having a plurality of pixels arranged thereon;

a plurality of gate and source drivers for supplying signals to the pixels;

a controller for supplying control signals to the gate and source drivers;

at least one conductive line at a corner portion of the first substrate, the conductive line connecting the controller and the gate drivers; and

a plurality of transparent electrodes along the extension direction of the corresponding conductive line to be overlapped with the conductive line with at least one intermediate film interposed therebetween, each transparent electrode being divided into a plurality of transparent electrode segments isolated from each other in the extension direction of the corresponding conductive line.

2. The panel according to claim 1 , wherein a direction of the conductive line is parallel with a direction of the overlapping transparent electrode segments.

3. The panel according to claim 1 , wherein the conductive line transmits DC signals including a gate high voltage (Vgh), a gate low voltage (Vgl), a common voltage (Vcom), a ground voltage (GND), and a power supply voltage (Vcc), and transmit AC signals including a gate start pulse (GSP), a gate shift clock (GSC), and a gate enable signal (GOE).

4. The panel according to claim 1 , wherein the intermediate film includes a gate insulation film.

5. The panel according to claim 1 , wherein the intermediate film includes at least one layer of a gate insulation film, a semiconductor layer, and a passivation film.

6. The panel according to claim 5 , wherein the passivation film includes an organic material having at least one of benzocyclobutene (BCB), a spin-on-glass (SOG), and photoacryl.

7. The panel according to claim 1 , wherein a pixel electrode is applied as the transparent electrode.

8. The liquid crystal display panel according to claim 1 , further comprising a seal pattern attaching the first substrate and a second substrate together within a seal pattern region such that a portion of the conductive line is within the seal pattern region.
