Abstract:
A display device includes: 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. The electric field inhibition film has a higher permittivity than the first underlying film.
