Abstract
To provide a display device, an electronic apparatus, or a lighting device that are hard to be damaged.SOLUTION: A first substrate having flexibility and a second substrate having flexibility are overlapped via a display element. A third substrate having flexibility is attached onto an external side of the first substrate, and a fourth substrate having flexibility is attached to an external side of the second substrate. The third substrate is formed of a material softener than that of the first substrate, The fourth substrate is formed of a material softener than that of the second substrate.SELECTED DRAWING: Figure 1
