Fabrication method of flat panel display comprising address line with mending layer

A method of fabricating a thin film transistor liquid crystal display comprising address lines with mending layers, the method comprising:

• forming a scan line, a gate and a first mending layer on a substrate, wherein the first mending layer is electrically insulated from the scan line and is partitioned into different segments by the scan line;
• forming an insulating layer over the substrate to cover at least the scan line, the gate and the first mending layer;
• forming a channel layer on the insulating layer over the gate;
• forming a heavily doped semiconductor layer on the channel layer;
• forming a data line on the insulating layer substantially over the first mending layer and crossing the scan line, wherein a portion of the data line formed over the heavily doped semiconductor layer as a source/drain conducting layer;
• forming a passivation layer over the substrate to cover at least the data line and a portion of the source/drain conducting layer, while the other portion of the source/drain conducting layer is exposed by an opening in the passivation layer;
• and
• forming a second mending layer on the passivation layer substantially over the data line and a pixel electrode to connect the exposed source/drain conducting layer, wherein the second mending layer crosses the scan line.
