Abstract
A display device includes a flexible first substrate, a flexible second substrate, a first layer, a first insulating layer in contact with the first layer, a second insulating layer in contact with the first layer, a liquid crystal layer between the first substrate and the second substrate, and a sealant sealing the liquid crystal layer and bonding the first substrate and the second substrate. The display device is bendable in a region inner to the sealant, the first substrate includes a seal region overlapping the sealant and a liquid crystal region overlapping the liquid crystal layer, the first insulating layer is in contact with the first layer in the seal region, the second insulating layer is in contact with the first layer in the liquid crystal region, and the first insulating layer and the second insulating layer have different thicknesses or are formed of different materials.
