Abstract: A highly reliable light-emitting device is provided. Damage to an element due to externally applied physical power is suppressed. Alternatively, in a process of pressure-bonding of an FPC, damage to a resin and a wiring which are in contact with a flexible substrate due to heat is suppressed. A neutral plane at which stress-strain is not generated when a flexible light-emitting device including an organic EL element is deformed, is positioned in the vicinity of a transistor and the organic EL element. Alternatively, the hardness of the outermost surface of a light-emitting device is high. Alternatively, a substrate having a coefficient of thermal expansion of 10 ppm/K or lower is used as a substrate that overlaps with a terminal portion connected to an FPC.
