Abstract:
A display device with a high luminance, a high contrast, and low power consumption is provided. The display device includes a transistor, a light-emitting element, a coloring layer, a phosphor layer, a first electrode, and a second electrode. The light-emitting element is electrically connected to the first electrode and the second electrode, the first electrode is electrically connected to the transistor, and the second electrode is positioned on the same plane as the first electrode. The coloring layer is positioned over the light-emitting element, the phosphor layer is positioned between the light-emitting element and the coloring layer, and the phosphor layer, the light-emitting element, and the coloring layer include a region in which they overlap with one another. The light-emitting element includes a light-emitting diode chip, and the phosphor layer has a function of emitting light of a complementary color of an emission color of the light-emitting element.
