According to one embodiment, a display device includes a flexible base, a display area, first lines arranged in a first direction, pixel electrodes, and a first inorganic insulating layer contacting the lines. The display area includes a first area in which the lines are arranged in the first direction at a first pitch and a second area in which the lines are arranged in the first direction at a second pitch greater than the first pitch, and the second area is located between the first area and an edge of the base in the first direction. In the second area, the first inorganic insulating layer comprises a first slit extending along the lines between adjacent lines.
