LCD device with data/gate line pad electrodes and contact electrode including both a transparent conductive film and a metal layer interconnecting data link and data line through respective contact holes

A liquid crystal display device, comprising:

• first and second substrates;
• a gate line on the first substrate;
• a gate insulating film on the first substrate;
• a data line crossing the gate line to define a pixel area;
• a thin film transistor connected to the gate line and the data line;
• an organic insulating film on the gate line, the data line and the thin film transistor, and having a transmission hole in the pixel area;
• a pixel electrode on the organic insulating film of the pixel area and in the transmission hole and connected to the thin film transistor;
• a reflective electrode on the pixel electrode having a same edge part as the pixel electrode or an edge part located at inner side from an edge part of the pixel electrode and exposing the pixel electrode of the transmission hole,
• wherein a source electrode is connected to the data line and a drain electrode is connected to the pixel electrode, and the organic insulating film, which is a single layer, contacts with the source electrode, the drain electrode and the pixel electrode,
• a pad connected to at least one of the gate line and data line;
• a lower pad electrode connected to at least one of the gate line and data line;
• a contact hole passing through the organic insulating film and the gate insulating film to expose the lower pad electrode;
• an upper pad electrode connected to the lower pad electrode via the contact hole;
• a data link extended from the lower pad electrode and adjacent to the data line;
• a plurality of contact holes exposing the data link and the data line;
• and
• a contact electrode passing through the contact holes to connect to the data link and the data line, and including a transparent conductive film same as the pixel electrode and a reflective metal layer same as the reflective electrode.
