  • Patent number: 8233122
    Abstract: A liquid crystal display device has pixel regions defined by gate lines and data lines perpendicular to the gate lines. The gate electrodes of thin film transistors (TFTs) at a first side of the data lines project from the gate lines. Active layers are disposed on the gate electrodes. Source electrodes overlap the active layers. Drain electrodes are parallel to the gate lines, spaced from the source electrodes and overlap the active layers. Pixel electrodes formed on the pixel region are connected to the drain electrodes. This structure prevents poor picture quality by minimizing the differences between the parasitic capacitance formed between the gate electrode and the drain electrode in adjacent pixel regions even if Y- or X-axis misalignment occurs.
