Patent ID: 8916858

Claim:
A display device, comprising: a substrate; a thin film transistor provided on the substrate, the thin film transistor including: a gate electrode provided on the substrate; a gate insulating film provided on the gate electrode; a semiconductor film provided on the gate insulating film, the semiconductor film including an oxide semiconductor containing at least one of In, Ga, and Zn; a first conducting portion electrically connected to the semiconductor film; and a second conducting portion electrically connected to the semiconductor film and provided apart from the first conducting portion; a pixel electrode electrically connected to one of the first conducting portion and the second conducting portion; an organic light emitting layer provided on the pixel electrode; a common electrode provided on the organic light emitting layer; and a sealing unit provided on the common electrode, the sealing unit including: a first sealing film having a hydrogen concentration of 10 20 atoms/cm 3 or less; and a second sealing film stacked on the first sealing film and having a hydrogen concentration of 10 20 atoms/cm 3 or less, a refractive index of the second sealing film being different from a refractive index of the first sealing film.
