Liquid crystal display device

A liquid crystal display device, comprising:

• at least two insulating layers formed on a first conductive layer;
• a second conductive layer formed between the at least two insulating layers;
• a first contact hole penetrating an upper insulating layer of the at least two insulating layers and exposing a portion of the second conductive layer;
• a second contact hole penetrating the at least two insulating layers and exposing a portion of the first conductive layer;
• and
• a contact part comprising a bridge electrode formed of a third conductive layer to electrically connect the first conductive layer to the second conductive layer through the first and second contact holes,
• wherein the second contact hole comprises an internal hole penetrating the at least two insulating layers and an external hole surrounding the internal hole and formed in the upper insulating layer,
• wherein the internal hole of the second contact hole and the external hole of the second contact hole are separated from each other by a given distance,
• wherein the first contact hole and the external hole of the second contact hole have a gently sloping surface as compared to a sloping surface of the internal hole of the second contact hole.
