A display device has an insulating substrate with a first surface and a second surface, a display element having an organic light-emitting layer arranged between two electrodes, a flexible member having a first end connected to the first surface and a second end facing the first end and the first surface, and a first accommodating member having a lower surface substantially parallel with the insulating substrate, a lateral surface extending from the lower surface, and a protruding part extending from the lower surface toward the first end. The first accommodating member includes a through hole, and the flexible member extends through the through hole so the second end is positioned outside the first accommodating member. The insulating substrate is arranged in the first accommodating member, and the protruding part may contact and press against the first end connected to the insulating substrate.
