Abstract
Provided is a display device capable of suppressing generation of optical leakage current as well as increase in capacitance in a case where a plurality of thin film transistors (TFTs) including a gate electrode film on a light source side are formed in series. Relative areas of opposing regions between a semiconductor film and the gate electrode film with respect to channel regions are different in at least a part of the plurality of TFTs, to thereby provide a flat panel display having a structure for suppressing increase in capacitance while suppressing generation of optical leakage current.
