Display device having island-shaped conductor for repairing line disconnection
View Patent ↗A liquid crystal display device has a gate line formed on a substrate, and a gate insulating film deposited thereon. On the gate insulating film are provided a source line, and a conductive layer above the gate line. An insulating layer is formed thereon, and a pixel electrode is then provided. The conductive layer does not contact the source line, and at least two portions of the conductive layer are electrically connected with the gate line.
1. A display device having a plurality of pixels, comprising:
a substrate;
a gate line provided on the substrate;
a first insulating layer provided on the gate line;
a plurality of source lines at least partially overlapping the gate line with the first insulating layer interposed therebetween;
a plurality of island-shaped conductors for repairing gate line disconnection, provided above the gate line with the first insulating layer interposed therebetween, the plurality of island-shaped conductors provided between and adjacent the source line;
a switching element controlling a signal to a pixel;
a second insulating layer with a through hole, provided on the switching element and the plurality of island-shaped conductors; and
a pixel electrode provided above the switching element with the second insulating layer interposed therebetween and connected with the switching element via the through hole, the pixel electrode partially overlapping the plurality of island-shaped conductors.
2. A display device according to claim 1 , wherein the plurality of island-shaped conductors are provided at both ends of the gate line in one pixel.
3. A display device according to claim 1 , wherein the gate line disconnection is repaired by connecting the gate line and the pixel electrode via the plurality of the island-shaped conductors disposed at both ends of a disconnected portion of the gate line.
4. A display device according to claim 3 , wherein the switching element is separated from the pixel electrode corresponding to the disconnected portion.
