摘要：
A polysilicon pattern constituting an active portion of a TFT is formed on a substrate so as to be curved to generally assume a U shape, and a gate pattern is formed as a straight conductor pattern. The gate pattern is so disposed as to cross the U-shaped polysilicon pattern plural times. The silicon pattern comprise a plurality of channel regions and impurity regions of which alignment is symmetrical.
