Liquid crystal display panel
View Patent ↗A display panel includes an array substrate including a plurality of connection lines extending from a plurality of signal lines and at least one repair line crossing the connection lines. An opposite substrate including a common electrode formed on a surface of the second substrate that is closest to the array substrate is coupled to the array substrate. The common electrode includes a plurality of openings that are positioned to align with a plurality of intersections between the connection lines and the repair line, thereby preventing an electrical coupling between the signal line and the common electrode.
1. A display panel comprising:
an array substrate comprising a first substrate having a display region and a peripheral region, a plurality of signal lines provided in the display region, a plurality of pixels connected with the signal lines, a plurality of connection lines provided in the peripheral region and extending from the signal lines, and at least one repair line crossing the connection lines; and
an opposite substrate coupled to the array substrate and comprising a second substrate and a common electrode that is formed on a surface of the second substrate that is closest to the array substrate, the common electrode comprising a plurality of openings that are positioned to align with a plurality of intersections between the connection lines and the repair line.
2. The display panel of claim 1 , wherein the openings correspond to the intersections in a one-to-one correspondence.
3. The display panel of claim 1 , wherein a plurality of repair lines are provided such that the connection lines cross the repair lines, respectively, and the openings correspond to the connection lines in a one-to-one correspondence.
4. The display panel of claim 3 , wherein the openings cover a plurality of intersections of the repair lines and the connection lines.
5. The display panel of claim 4 , wherein each opening has a rectangular shape or an oval shape.
6. The display panel of claim 1 , wherein each connection line comprises a first connection line connected with one end of a particular signal line and a second connection line connected with an opposite end of the particular signal line, and the repair line comprises a first repair line crossing the first connection line and a second repair line crossing the second connection line.
7. The display panel of claim 6 , wherein the repair line further comprises a repair connection line formed in the peripheral region to electrically connect the first repair line to the second repair line.
8. The display panel of claim 7 , wherein the repair line is provided in plurality and the repair connection line comprises first and second repair connection lines positioned across the display region from each other.
9. The display panel of claim 6 , wherein the signal lines comprise a plurality of gate lines to supply a gate signal to the pixels and a plurality of data lines crossing the gate lines to supply a data signal to the pixels.
10. The display panel of claim 9 , further comprising:
a gate driver provided in the peripheral region to supply the gate signal to the gate lines; and
a data driver provided in the peripheral region to supply the data signal to the data lines.
11. The display panel of claim 10 , wherein the data driver comprises an amplifier to amplify the data signal and supply the data signal to the second repair line.
12. The display panel of claim 11 , wherein the repair line further comprises a repair connection line to deliver the amplified data signal to the second repair line.
13. The display panel of claim 1 , wherein the array substrate further comprises a common voltage line formed in the peripheral region of the first substrate to supply the common voltage, which is provided from the outside, to the conductive spacer.
14. The display panel of claim 13 , wherein the conductive spacer comprises a plurality of first conductive spacers and a plurality of second conductive spacers positioned across the display region from the first conductive spacers.
15. The display panel of claim 14 , wherein the first and second conductive spacers are provided between the repair line and the edge of the first substrate.
16. The display panel of claim 1 further comprising a conductive spacer interposed between the array substrate and the opposite substrate and configured to deliver a common voltage to the common electrode.
