摘要： A display device includes: a resin substrate, and a thin film transistor layer, wherein in the thin film transistor layer, a first thin film transistor and a second thin film transistor are provided for each of subpixels. The first thin film transistor includes a first semiconductor layer formed of polysilicon, a first gate electrode provided on the resin substrate side of the first semiconductor layer via a first gate insulating film, and a metal layer provided on a side opposite to the resin substrate side of the first semiconductor layer via a first interlayer insulating film. The second thin film transistor includes a second semiconductor layer formed of an oxide semiconductor, and a second gate electrode provided on a side opposite to the resin substrate of the second semiconductor layer via a second gate insulating film.
