Abstract
A novel display device that is highly convenient with low power consumption is provided. The display device includes a display element including a liquid crystal layer, a display element including a light-emitting layer, and a pixel circuit. Electrodes of the display element including the liquid crystal layer and the display element including the light-emitting layer are electrically connected to the pixel circuit. The electrode of the display element including the liquid crystal layer includes a reflective film including an opening. The pixel circuit includes a transistor including a semiconductor film. The number of insulating films in a region overlapping with the opening is smaller than that of insulating films overlapping with the semiconductor film. In addition, the display element including the light-emitting layer includes two light-emitting elements. The number of optical elements overlapping with one light-emitting element is smaller than that of optical elements overlapping with the other light-emitting element.
