摘要：
A current-drive thin-film transistor display apparatus that simultaneously achieves a reduction in the off-current of a switching thin-film transistor and an increase in the on-current of a current thin-film transistor.In an exemplary embodiment, the switching thin-film transistor is formed as a transistor of lightly doped drain structure or offset structure while the current thin-film transistor is formed as a transistor of self-alignment structure. Alternatively, each of the switching thin-film transistor and the current thin-film transistor is formed as a transistor of lightly doped drain structure or offset structure, and the lightly doped drain length or offset length of the switching thin-film transistor is increased relative to that of the current thin-film transistor.
