An electronic device where the amount of data transfer is reduced is provided. The electronic device is a head-mounted type electronic device that includes a display panel, an optical device, and a direction detection sensor. A display portion of the display panel includes a first region including a pixel array center, a second region adjacent to the outside of the first region, and a third region adjacent to the outside of the second region. The definition of the first region is higher than the definition of the second region, and the definition of the second region is higher than the definition of the third region. Head tracking using the direction detection sensor makes video of the display portion follow a user's head movement so that a user's line of sight can be maintained in the first region that has the highest definition.
