Abstract
Disclosed are a backplane substrate, which is devised to attain circuit characteristics for realizing sufficient gradation even in smaller pixels of a super-high-resolution structure, a manufacturing method for the same, and an organic light-emitting display device using the same, inn the backplane substrate, a driving thin-film transistor has a stack structure different from that of other thin-film transistors so that only the S-factor of the driving thin-film transistor is increased.
