Display device having an electric field infibition film

A display device comprising:

• a substrate configured to contain an organic material;
• a first underlying film provided above the substrate;
• a thin film transistor provided above the first underlying film;
• a semiconductor film included in the thin film transistor and configured to have a channel region;
• and
• an electric field inhibition film provided between the first underlying film and the semiconductor film and configured to overlap the channel region in a plan view, wherein
• the electric field inhibition film has a higher permittivity than the first underlying film,
• a display region including a plurality of pixels and a peripheral region located outside of the display region are included above the substrate,
• a driving circuit that drives the plurality of pixels is located in the peripheral region,
• the thin film transistor is included in the driving circuit, and
• the electric field inhibition film is located in the peripheral region.
