Abstract: Malfunction of a large-sized touchscreen is prevented. In particular, malfunction of a large-sized touchscreen is prevented by reduction of wiring delay between a detection region and a controller. In a touchscreen, in which a detection area is divided, including a plurality of detection regions and a plurality of sensors, controllers are provided for the respective divided detection regions, and all the controllers are electrically connected to one central control device. It is preferable that a wiring between each of the divided detection regions and the corresponding controller be shorter than a wiring between the controller and the central control device.

Abstract: A light-emitting element with high emission efficiency. The light-emitting element includes a pair of electrodes and an EL layer between the pair of electrodes. In the light-emitting element, the EL layer contains at least a light-emitting material, the light-emitting material is a 1,6-bis(diphenylamino)pyrene derivative, and a structural change between an excited state and a ground state in the 1,6-bis(diphenylamino)pyrene derivative is smaller than that in a 1,6-bis(diphenylamino)pyrene derivative in which hydrogen is bonded to ortho positions of two phenyl groups of each of two diphenylamino groups.
