Abstract:
A thin-film transistor comprising:a semiconductor pattern formed over a substrate comprising a plurality of channel regions and a plurality of first diffusion regions formed on both sides of each of said channel regions, said semiconductor pattern having at least one curved portion;a gate pattern which is a straight conductor pattern and is placed to cross said semiconductor pattern plural times;a source line connected with a first one of said first diffusion regions; anda pixel electrode connected with a second one of said first diffusion regions,wherein at least a third one of the first diffusion regions is disposed between said first one and second one of the first diffusion regions,wherein said semiconductor pattern further comprises, between each channel region and each first diffusion region, a plurality of second diffusion regions having a lower impurity concentration than said first diffusion regions,wherein two of said second diffusion regions, which are contiguous to said first and second ones of the first diffusion regions, respectively, have a same width, andwherein said width of said two second diffusion regions is larger than widths of others of the second diffusion regions.
