Display device including light emitting units emitting the same color

A display device, comprising:

• a first light emitting unit;
• a first optical portion disposed on the first light emitting unit, wherein a light emitting from the first light emitting unit at least passes through the first optical portion is a first light, and the first light comprises a first main-peak;
• a second light emitting unit;
• a second optical portion disposed on the second light emitting unit, wherein a light emitting from the second light emitting unit at least passes through the second optical portion is a second light, and the second light comprises a second main-peak;
• wherein a first wavelength difference between the first main-peak and the second main-peak is less than 20 nm, and the first light and the second light are same color light,
• wherein a wavelength of the first main-peak is more than or equal to 460 nm and less than or equal to 470 nm, and a wavelength of the second main-peak is more than or equal to 460 nm and less than or equal to 470 nm.
