Abstract
A display device, an electronic device, or a lighting device that is unlikely to be broken is provided. A flexible first substrate and a flexible second substrate overlap with each other with a display element provided therebetween. A flexible third substrate is bonded on the outer surface of the first substrate, and a flexible fourth substrate is bonded on the outer surface of the second substrate. The third substrate is formed using a material softer than the first substrate, and the fourth substrate is formed using a material softer than the second substrate.
