Patent attributes
A display device with high driving performance is provided. The display device includes a base, a display portion, a gate deriver, a level shifter, a source driver IC, and a controller IC. Each of the display portion, the gate driver, and the level shifter includes a transistor including a metal oxide in a channel formation region and is formed over the base. Each of the source driver IC and the controller IC includes a transistor including silicon in a channel formation region and is mounted over the base. The display portion is electrically connected to the gate driver and the source driver IC. The gate driver is electrically connected to the controller IC through the level shifter, and the source driver IC is electrically connected to the controller IC.
