Abstract: Warpage deformation which is caused when substrates having mutually different linear expansion coefficients are bonded to sandwich a display functional layer is suppressed. A display device has a first substrate, a second substrate bonded to the first substrate so as to be opposed to the first substrate, and a liquid crystal layer serving as a display functional layer disposed between the first substrate and the second substrate. Also, a first linear expansion coefficient of the first substrate provided in the display device is larger than a second linear expansion coefficient of the second substrate, and a first thickness of the first substrate is larger than a second thickness of the second substrate.
