Abstract:
A display device includes a plurality of emitting elements corresponding to a plurality of pixels. The emitting element includes a lower electrode, an upper electrode having a light-transmitting property, and a light-emitting layer between the lower electrode and the upper electrode. The lower electrode includes a flat portion and an inclined portion that is inclined obliquely upward and outward from the central area of the flat portion. Both of the flat portion and the inclined portion include a reflective surface respectively. The reflective surface of the flat portion has a light reflectance lower than that of the reflective surface of the inclined portion.
