Patent ID: 7616284

Claim:
A liquid crystal display device, comprising: first and second substrates; a gate line on the first substrate; a data line crossing the gate line having a gate insulating film therebetween to define a pixel area; a pixel electrode formed of a transparent conductive film in a pixel hole passing through the gate insulating film in the pixel area; a thin film transistor including a gate electrode, a source electrode, a drain electrode, and a semiconductor layer defining a channel between the source electrode and the drain electrode, wherein the semiconductor layer overlaps with a source and drain metal pattern including the data line, the source electrode and the drain electrode, and the drain electrode protrudes from the semiconductor layer toward inside of the pixel electrode to be connected to the pixel electrode; a pad connected to at least one of the gate line and the data line, wherein the pad includes a lower pad electrode on the first substrate, a first contact hole passing through the gate insulating film to expose the lower pad electrode, and an upper pad electrode in the first contact hole connected to the lower pad electrode; a data link extending from the lower pad electrode to overlap with the data line; and a contact electrode in a second contact hole passing through the gate insulating film to expose the data link, thereby connecting the data link to the data line, wherein a transparent conductive pattern including the pixel electrode, the upper pad electrode, and the contact electrode borders with the gate insulating film enclosing the corresponding hole.
