Abstract
The disclosure provides a display device including red, green and blue pixel units. In the red pixel unit, a light emitting element emits a blue light that then passes through a light conversion element and a color filter and the blue light is converted into a red light while passing through the light conversion element. In the green pixel unit, a light emitting element emits a blue light that then passes through a light conversion element and a color filter and the blue light is converted into a green light while passing through the light conversion element. In the blue pixel, a light emitting element emits a blue light that then passes through a color filter. The red pixel unit has a lighting area greater than a lighting area of the blue pixel unit and less than a lighting area of the green pixel unit.
