Abstract
According to one embodiment, a first distance is a distance between both ends of the first insulating film in a direction connecting the fourth semiconductor layer and the sixth semiconductor layer. The first distance in the first region is longer than the first distance in the second region. A second distance is a distance between an edge of the second insulating film on an inner peripheral side of the second semiconductor layer and an edge of the third semiconductor layer on an outer peripheral side of the second semiconductor layer. The second distance in the first region is shorter than the second distance in the second region.
