摘要： A highly reliable display device is provided. The display device includes a first substrate, a first resin layer over the first substrate, a pixel portion and a terminal portion over the first resin layer, a second resin layer over the terminal portion, and a second substrate over the second resin layer. The pixel portion includes a transistor and a display element electrically connected to the transistor. The terminal portion includes a conductive layer. The first resin layer includes an opening. The conductive layer includes a first region that is exposed in the opening in the first resin layer. The second resin layer includes a region overlapping with the first region. The conductive layer is the same layer as at least one of a gate of the transistor and a source and a drain of the transistor.

摘要： To provide a peeling method that achieves low cost and high mass productivity. The peeling method includes the steps of: forming a first layer with a photosensitive material over a formation substrate; forming a first region and a second region having a smaller thickness than the first region in the first layer by photolithography to form a resin layer having the first region and the second region; forming a transistor including an oxide semiconductor in a channel formation region over the first region in the resin layer; forming a conductive layer over the second region in the resin layer; and irradiating the resin layer with laser light to separate the transistor and the formation substrate.

摘要： A first display element includes a first pixel electrode that reflects visible light, a liquid crystal layer, and a first common electrode that transmits visible light. A second display element includes a second pixel electrode that transmits visible light, a light-emitting layer, and a second common electrode that reflects visible light. A separation layer that reflects visible light is formed over a formation substrate, an insulating layer is formed over the separation layer, and the second display element is formed over the insulating layer. The formation substrate and a second substrate are bonded to each other. Then, the formation substrate and the separation layer are separated from each other. The exposed separation layer is processed into the first pixel electrode. The liquid crystal layer is positioned between the first common electrode and the first pixel electrode and a first substrate and the second substrate are bonded to each other.

摘要： A display device or an electronic device with high portability and browsability is provided. A display device which includes two display panels that overlap with each other and in which the area of a portion where the two display panels overlap with each other is variable is provided. The larger the area where the two display panels overlap with each other is, the smaller the display device becomes. The first display panel includes a first region that performs display. The second display panel includes a second region that performs display, and a third region that is adjacent to the second region and transmits visible light. When the third region overlaps with the side of a surface which performs display of the first region, display can be performed using a seamless large display region.

摘要： 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.
