Structure of switching device for liquid crystal display device and fabrication method thereof
View Patent ↗A thin film transistor of an LCD device and a fabrication method thereof fabricates the thin film transistor of the LCD device including a source electrode unit of ‘U’ shape and a drain electrode of straight line shape formed as entering into a concave portion of the source electrode and a channel layer formed between the source electrode and a longer side of the drain electrode in fabricating the thin film transistor using a slit mask, and thereby, the LCD having even device property can be fabricated and inferiority such as short-circuit of the channel can be solved.
1. A switching device of an LCD comprising:
a source electrode of ‘U’ shape;
a drain electrode formed on a concave portion of the source electrode; and
a channel layer formed between the source electrode and a longer side of the drain electrode, wherein the channel layer is formed between the source electrode and the long side of the drain electrode by the slit mask of single direction, and a channel is not formed between a short side of the drain electrode and the source electrode.
