Display device

A display device comprising:

• a first substrate including a first resin substrate formed of a first resin material, the first resin material having a first thermal expansion coefficient;
• a first barrier layer formed on the first resin substrate, the first barrier layer having a second thermal expansion coefficient;
• a display portion formed on the first barrier layer and including a light emitting element and a sealing film covering the light emitting element;
• a mounting portion formed on the first barrier layer;
• a second substrate including a second resin substrate formed of a second resin material, the second resin material having a third thermal expansion coefficient;
• and
• a second barrier layer formed on the second resin substrate, the second barrier layer having a fourth thermal expansion coefficient, wherein
• the first resin substrate and the second resin substrate are transparent,
• the second thermal expansion coefficient is lower than the first thermal expansion coefficient,
• the fourth thermal expansion coefficient is lower than the third thermal expansion coefficient,
• the first resin substrate is in contact with a first surface of the first barrier layer,
• the second resin substrate is in contact with the second barrier layer,
• a switching element is formed on the first barrier layer,
• the light emitting element is electrically connected to the switching element, and
• the first substrate and the second substrate are attached to each other with an insulating adhesive.
