Abstract: A display system with high display quality in which display unevenness is reduced is provided. The display system includes a processing unit and a display portion. The processing unit generates second image data by using first image data. The display portion displays an image on the basis of the second image data. The processing unit includes three layers. The first image data is supplied to the first layer. The first image data contains a plurality of pieces of data. The plurality of pieces of data each correspond to any one of the plurality of pixels. The first layer generates first arithmetic data by making the number of data corresponding to one pixel larger than the number of the first image data by using the first image data. The second layer generates second arithmetic data by multiplying the first arithmetic data by a weight coefficient. The third layer generates the second image data by making the number of data corresponding to one pixel smaller than the number of the second arithmetic data by using the second arithmetic data.

Abstract: A display device that can easily have high resolution is provided. A display device having both high display quality and high resolution is provided. A display device with high contrast is provided. A first EL film is deposited in contact with a top surface and a side surface of each of a first pixel electrode and a second pixel electrode each having a tapered shape. A first sacrificial film is formed to cover the first EL film. The first sacrificial film and the first EL film are etched to expose the second pixel electrode and form a first EL layer over the first pixel electrode and a first sacrificial layer over the first EL layer, and then, the first sacrificial layer is removed. The first EL film and the second EL film are etched by dry etching. The first sacrificial layer is removed by wet etching.
