Abstract

A display apparatus having both a personal authentication function and a high resolution is provided. The display apparatus includes a display portion and a sensor portion. The display portion includes a first light-emitting element and a second light-emitting element. The first light-emitting element includes a first EL layer. The second light-emitting element includes a second EL layer. The sensor portion includes a light-receiving element. The first light-emitting element has a function of emitting infrared light. The light-receiving element has a function of detecting infrared light. A distance between the first EL layer and the second EL layer is less than or equal to 6 μm.
