An electronic device includes a first electronic unit and a second electronic unit. The first electronic unit includes a first light conversion layer and emits a blue light having a first spectrum. The first spectrum has a first intensity, and the first intensity is a maximum intensity of the first spectrum. The second electronic unit emits a light having a second spectrum different from the first spectrum, and the second spectrum has a second intensity in a range from 300 nm to 460 nm, and the second intensity is a maximum intensity in the range from 300 nm to 460 nm of the second spectrum. A ratio of the second intensity to the first intensity is in a range from 0.06% to 10.0%.
