Abstract
A repair structure including a substrate, at least one first conducting line, a first insulating layer, at least one second conducting line and a repair connecting layer is provided. The at least one first conducting line is disposed on the substrate. The first insulating layer is disposed over the substrate to cover the first conducting line. The second conducting line is disposed over the first insulating layer. The second insulating layer covers the second conducting line and the first insulating layer. The repair connecting layer is disposed on the second insulating layer. In particular, the repair connecting layer is electrically connected to the first conducting line. The repair connecting layer overlaps the second conducting line but is electrically insulated from the second conducting line.
Claims13
An active device array substrate, comprising:
- a substrate having a display region and a peripheral circuit region surrounding the display region;
- a pixel array disposed in the display region of the substrate;
- and
- a repair structure, disposed in the peripheral circuit region of the substrate, the repair structure comprising
- at least one repair line,
- a first insulating layer covering the repair line,
- at least one second conducting line disposed over the first insulating layer and electrically connected with the pixel array,
- a second insulating layer covering the second conducting line and the first insulating layer, and
- at least one repair connecting layer having a continuous pattern, the repair connecting layer being disposed on the second insulating layer, electrically connecting with the repair line and overlapping the second conducting line, wherein the repair connecting layer is electrically insulated from the second conducting line
- wherein the repair line surrounds the display region, the at least one second conducting line includes a plurality of second conducting lines extending from the display region to the peripheral circuit region and being electrically connected with the pixel array, the at least one repair connecting layer includes a plurality of repair connecting layers disposed on the second insulating layer, each of the repair connecting layers is electrically connecting with the repair line and overlapped with one of the second conducting lines respectively, and the repair connecting layers are electrically insulated from the second conducting lines, and
- each of the second conducting lines has two ends located at the peripheral circuit region, the two ends of one of the second conducting lines are overlapped with different repair connecting layers respectively.
A repair structure, comprising:
- a substrate;
- at least one repair line disposed on the substrate;
- a first insulating layer disposed over the substrate to cover the repair line;
- at least one second conducting line disposed over the first insulating layer;
- a second insulating layer covering the second conducting line and the first insulating layer;
- and
- a repair connecting layer having a continuous pattern, the repair connecting layer being disposed on the second insulating layer and electrically connecting with the repair line, the repair connecting layer being overlapped with the second conducting line, wherein the repair connecting layer only electrically contacts with the repair line and is electrically insulated from the second conducting line.
