Abstract
A switching element (a semiconductor device) (18) having a top gate electrode (21) and a bottom gate electrode (23) is provided with a silicon layer (a semiconductor layer) (SL) that is arranged between the top gate electrode (21) and the bottom gate electrode (a light-shielding film) (23) and that has a source region (24), a drain region (28), a channel region (26), and low-concentration impurity regions (25, 27). Furthermore, the bottom gate electrode (23) is arranged so as to overlap the channel region (26), a part of the low-concentration impurity region (25), which is adjacent to the source region (24), and a part of the low-concentration impurity region (27), which is adjacent to the drain region (28). The bottom gate electrode (23) is controlled so as to have a prescribed potential.
