Display

A display comprising:

• a substrate;
• and
• a thin film transistor layer disposed on the substrate and including a thin film transistor for each of sub-pixels constituting a display region,
• wherein the thin film transistor includes:
• a semiconductor layer composed of an oxide semiconductor and including a source region and a drain region defined to be separate from each other and a channel region defined between the source region and the drain region;
• a first gate electrode disposed on a side of the semiconductor layer facing the substrate, the first gate electrode overlapping the channel region with a first gate insulating film therebetween;
• and
• a second gate electrode disposed on a side of the semiconductor layer facing away from the substrate, the second gate electrode overlapping the channel region with a second gate insulating film therebetween, and
• the semiconductor layer has a planar shape due to an organic insulating film disposed on the side of the semiconductor layer facing the substrate, the organic insulating film overlapping at least the source region and the drain region.
