Abstract
A highly reliable display apparatus is provided at a low cost. The display apparatus includes a light-emitting diode included in a pixel circuit, a transistor included in the pixel circuit, and a transistor included in a driver circuit of the pixel circuit, which are stacked to have an overlap region. With such a structure, the display apparatus can be downsized. In addition, in the display apparatus, a plurality of light-emitting diodes can be attached to a circuit board formed with a transistor and the like in one step. Consequently, the manufacturing cost of the display apparatus can be reduced.
