Abstract
The display panel includes a light emitting device, three quantum dot converters including quantum dot particles and converting light of a first color emitted from the light emitting device to light of a different color and emitting the light of the different color, a transmission part transmitting light of the first color emitted from the light emitting device, and a transparent substrate disposed on one side of the three quantum dot converters and the transmission part. One of the three quantum dot converters emits a white light to the transparent substrate.
