Abstract
To prevent a point defect and a line defect in forming a light-emitting device, thereby improving the yield. A light-emitting element and a driver circuit of the light-emitting element, which are provided over different substrates, are electrically connected. That is, a light-emitting element and a driver circuit of the light-emitting element are formed over different substrates first, and then electrically connected. By providing a light-emitting element and a driver circuit of the light-emitting element over different substrates, the step of forming the light-emitting element and the step of forming the driver circuit of the light-emitting element can be performed separately. Therefore, degrees of freedom of each step can be increased, and the process can be flexibly changed. Further, steps (irregularities) on the surface for forming the light-emitting element can be reduced than in the conventional technique.
