Patent ID: 8023054

Claim:
A flat panel display device, comprising: a gate line and a data line crossing each other to define a pixel area; a pixel electrode in the pixel area; a thin film transistor having a gate electrode connected to the gate line, a source electrode connected to the data line, a drain electrode connected to the pixel electrode; a gate insulating film disposed on the gate line and the gate electrode; and an active layer and an ohmic contact layer sequentially disposed on the gate insulating film, wherein the gate line has at least two or more separated gate line portions at a crossing region where the gate line crosses the data line, the at least two or more separated gate line portions overlapping the data line at the crossing region, and the source electrode of the thin film transistor has at least two separated source electrode portions extending from another source electrode portion toward a channel part of the thin film transistor, wherein the two or more separated gate line portions are connected to another gate line portion and the gate electrode; and wherein the two or more separated gate line portions have the same length between the another gate line portion and the gate electrode.
