Abstract
There is disclosed a liquid crystal display device that is adaptive for preventing the driving device defect of a driving circuit part and a method of fabricating the same. A liquid crystal display device according to an embodiment of the present invention includes a driving device of a structure that a plurality of thin film transistor having a channel of poly silicon are connected in parallel, in a driving circuit, and wherein at least one of widths of the channels and distances between the adjacent channels is different in accordance with their location.
Claims4
A liquid crystal display device, comprising:
- a driving device of a structure that a plurality of thin film transistor having a channel of poly silicon are connected in parallel, in a driving circuit, and
- wherein at least one of widths of the channels and distances between the adjacent channels is different in accordance with their location;
- wherein when the distance between the channels is uniform, the channel width is formed to be one of gradually broader as it goes from a central part of the driving device to the edge thereof, or when the channel width is uniform, the distance between the channels is formed to be gradually narrower as it goes from a central part of the driving device to the edge thereof.
A fabricating method of a liquid crystal display device, comprising:
- forming in a driving circuit a driving device of a structure that a plurality of thin film transistors are connected in parallel, wherein the thin film transistor has a channel of poly silicon;
- and
- forming at least one of the widths of the channels and distances of the channels in accordance with their location
- wherein when the distance between the channels is uniform, the channel width is formed to be gradually broader as it goes from a central part of the driving device to the edge thereof, or when the channel width is uniform, the distance between the channels is formed to be gradually narrower as it goes from a central part of the driving device to the edge thereof.
