Abstract

A display device that has high display quality is provided. A highly reliable display device is provided. A display device with low power consumption is provided and a display device that can easily achieve a higher resolution is provided. A display device with both high display quality and a high resolution is provided. A display device with high contrast is provided. The display device includes a first layer, a second layer over the first layer, and a third layer over the second layer. The first layer includes a first transistor including silicon in a channel formation region. The second layer includes a second transistor including a metal oxide in a channel formation region. The third layer includes a first light-emitting element, a second light-emitting element, a third light-emitting element, an EL layer including a light-emitting layer exhibiting white light, a first coloring layer over the first light-emitting element, a second coloring layer over the second light-emitting element, and a third coloring layer over the third light-emitting element. Crosstalk is not observed between the second light-emitting element and the third light-emitting element.
