摘要：
According to one embodiment, a display device includes a substrate, a thin film transistor, a pixel electrode, an organic light emitting layer, a common electrode, and a sealing unit. The thin film transistor is provided on the substrate. The thin film transistor includes a gate electrode, a gate insulating film, a semiconductor film, a first conducting portion, and a second conducting portion. The pixel electrode is electrically connected to one of the first conducting portion and the second conducting portion. The organic light emitting layer is provided on the pixel electrode. The common electrode is provided on the organic light emitting layer. The sealing unit is provided on the common electrode. The sealing unit includes a first sealing film and a second sealing film. A refractive index of the second sealing film is different from a refractive index of the first sealing film.
