Abstract

An electronic device includes a display panel including a first region, a second region, a third region, and a reflection prevention optical layer. A first light emission element is disposed in the first region, a second light emission element is disposed in the second region, and a third light emission element is disposed in the third region. The reflection prevention optical layer includes a first color filter overlapping the first light emission element, a second color filter overlapping the second light emission element, and a third color filter overlapping the third light emission element. The first color filter, the second color filter, and the third color filter transmit light of the same color, and the shape of the first color filter is different from the shape of the second color filter and the shape of the third color filter.
