Array substrate with reduced pixel defect, method of manufacturing the same and liquid crystal display panel having the same

A method of manufacturing an array substrate comprising:

• forming a gate line and a gate electrode connected the gate line on a transparent substrate;
• forming a channel layer extending in a first direction that is substantially parallel to the gate line on the gate electrode;
• forming a source line, a source electrode connected to the source line and a drain electrode to cover the channel layer;
• forming an insulating layer having a contact hole to partially expose the drain electrode and the transparent substrate;
• and
• forming a pixel electrode layer connected to the drain electrode through the contact hole on the insulating layer.

A liquid crystal display panel comprising:

• a liquid crystal layer;
• a first substrate;
• and
• a second substrate positioned substantially parallel to the first substrate and combined with the first substrate to receive the liquid crystal layer, the second substrate comprising:
• a transparent substrate;
• a switching element comprising a gate electrode formed on the transparent substrate and electrically connected to a gate line, a channel layer formed on the gate electrode and extended in a first direction, a source electrode connected to a source line, and a drain electrode formed on the channel layer to cover the channel layer;
• an insulating layer having a contact hole to partially expose the drain electrode and the transparent substrate;
• and
• a pixel electrode connected to the drain electrode through the contact hole.
