Beschreibung
Zusammenfassung:	Provided is a backlight module including a light source, a light guide plate, and a light conversion layer. The light source emits light. The light guide plate is optically coupled to the light source and the light transmits through the light guide plate. The light conversion layer is disposed on the light guide plate. The light conversion layer includes a first layer and a second layer. The first layer is adjacent to the light source and includes a plurality of first quantum dots. The second layer is further away from the light source than the first layer and includes a plurality of second quantum dots. An emission wavelength of the plurality of first quantum dots is greater than an emission wavelength of the plurality of second quantum dots.
