Identification mark portion in liquid crystal display panel and fabricating method thereof

A liquid crystal display panel comprising:

• a substrate having first region and second region;
• a thin film transistor in the first region, the thin film transistor including:
• a gate electrode on the substrate;
• a first insulating layer over the substrate;
• an active layer on the first insulating layer;
• source/drain electrodes on the active layer;
• and
• a second insulating layer over the substrate;
• an identification mark pad having an identification mark in the second region, the identification mark being exposed by an opening formed in at least one layer of the first and second layers;
• and
• a pixel electrode in the first region, wherein the pixel electrode is formed in the opening to cover at least a portion of the identification mark pad.

A liquid crystal display panel comprising:

• a substrate having first region and second region;
• a displaying element in the first region;
• an identification layer made of metal in the second region, the identification layer having a shape to identify the panel from another panel;
• and
• first and second insulating layers over the substrate, at least one insulating layer of the first and second insulating layers having an opening to expose at least a portion of the identification layer.

A method of fabricating a liquid crystal display panel, the method comprising the steps of:

• providing a substrate having first region and second region;
• forming thin film transistor in the first region, the thin film transistor including:
• a gate electrode on the substrate;
• a first insulating layer over the substrate;
• an active layer on the first insulating layer;
• source/drain electrodes on the active layer;
• and
• a second insulating layer over the substrate;
• forming an identification mark pad having an identification layer over the substrate in the second region;
• forming an opening in at least one layer of the first and second insulating layers to expose at least a portion of the identification mark pad to form an identification mark;
• and
• forming a pixel electrode in the first region.
