Abstract: According to one embodiment, a display device includes a first substrate, a second substrate, a liquid crystal layer including polymers and liquid crystal molecules, and a light-emitting element. The first substrate includes a transparent substrate, a scanning line, a signal line crossing the scanning line, a switching element electrically connected to the scanning line and the signal line, an organic insulating film overlapping the switching element, and a pixel electrode electrically connected to the switching element. A thickness of the organic insulating film located between the transparent substrate and the pixel electrode is less than a thickness of the organic insulating film overlapping the switching element.
