Liquid crystal display panel having a repair line positioned only underneath the second portion of the non-display area
View Patent ↗A liquid crystal display panel is provided. The LCD panel has a first substrate having at least a conductive material layer thereon, a second substrate having at least a repair line positioned in a predetermined area, and a liquid crystal layer positioned between the first substrate and the second substrate. The predetermined area is underneath the first substrate excluding the portions having the conductive material layer, thus reducing RC delay of the repair line.
1. An LCD panel comprising:
a first substrate comprising a display area and a non-display area including a first portion and a second portion;
at least a conductive material pattern positioned in the display area and only in the first portion, excluding the second portion, of the non-display area of the first substrate;
a second substrate having at least a repair line thereon, positioned in a predetermined area underneath the second portion of the non-display area of the first substrate, wherein the repair line repairs a disconnecting wire on the second substrate so that an external signal, which is predetermined to transmit to the wire, is capable of passing through the repair line to the wire, the repair line being positioned only underneath the second portion of the non-display area; and
a liquid crystal layer positioned between the first substrate and the second substrate.
2. The LCD panel of claim 1 wherein the first substrate is a CF substrate.
3. The LCD panel of claim 1 wherein the conductive material pattern is a transparent electrode.
4. The LCD panel of claim 3 wherein the conductive material pattern is defined by a shadow mask.
5. The LCD panel of claim 3 wherein the conductive material pattern is defined by a photolithography process.
6. The LCD panel of claim 1 wherein the first substrate further comprises a black matrix positioned in the first portion of the non-display area.
7. The LCD panel of claim 1 wherein the first substrate further comprises a main sealant positioned in the second portion of the non-display area for binding the first substrate and the second substrate.
8. The LCD panel of claim 7 wherein the main sealant covers the repair line.
9. The LCD panel of claim 7 wherein the main sealant covers a surface of the second substrate adjacent to the repair line.
10. The LCD panel of claim 1 wherein the second substrate is a TFT substrate.
11. The LCD panel of claim 1 wherein the second substrate has a plurality of thin-film transistors thereon for controlling operation of the pixels of the LCD panel.
12. The LCD panel of claim 11 wherein the predetermined area encloses the thin-film transistors.
13. The LCD panel of claim 1 wherein the line is a data line, and the external signal is a data signal.
14. The LCD panel of claim 1 wherein the liquid crystal layer is filled between the first substrate and the second substrate by the way of ODF (One Drop Filling).
15. The LCD panel of claim 6 wherein the conductive material pattern covers at least a portion of the black matrix.
16. The LCD panel of claim 9 wherein the repair line is positioned between the main sealant and the display area.
