1. An electronic device comprising a display apparatus, a gaze detection portion, and an arithmetic portion,
wherein the display apparatus comprises a display portion divided into a plurality of sub-display portions and a functional circuit comprising a luminance conversion circuit,
wherein the gaze detection portion is configured to detect a user's gaze,
wherein the arithmetic portion is configured to allocate the plurality of sub-display portions to a first section or a second section with the use of a detection result of the gaze detection portion,
wherein the functional circuit is configured to perform display on the sub-display portion included in the first section with a first driving frequency and perform display on the sub-display portion included in the second section with a second driving frequency lower than the first driving frequency,
wherein the sub-display portion included in the first section performs display based on first image data and black image data in one frame period,
wherein the sub-display portion included in the second section performs display based on second image data in one frame period,
wherein the luminance conversion circuit is configured to convert input image data into image data with reduced luminance to be displayed in the sub-display portion,
wherein the second image data is image data converted by the luminance conversion circuit,
wherein the plurality of sub-display portions each comprise a plurality of pixel circuits and a plurality of light-emitting elements,
wherein the display apparatus comprises a plurality of gate driver circuits and a plurality of source driver circuits,
wherein one of the plurality of gate driver circuits and one of the plurality of source driver circuits are electrically connected to one of the plurality of sub-display portions,
wherein the plurality of gate driver circuits and the plurality of source driver circuits are each provided in a first layer,
wherein the plurality of pixel circuits are provided in a second layer over the first layer, and
wherein the plurality of light-emitting elements are provided in a third layer over the second layer.
