Abstract: A liquid crystal display including a plurality of pixels that display an image, each pixel includes a thin film transistor that includes a gate electrode, a source electrode having a bar-shape and partially overlapping the gate electrode, and a drain electrode facing the source electrode at a location corresponding to the gate electrode, the drain electrode includes a first end portion having a C-shape that surrounds a distal end of the bar-shaped source electrode. This design eliminates an overlap between a data line and the gate electrode, which eliminates an overlap between the data line and the channel area of a semiconductor layer, which reduces a parasitic capacitor of the data line, resulting in less current to drive the data line, resulting in reduced power consumption of the display.
