1. A color filter unit comprising:
an upper substrate;
a first-color color filter layer, a second-color color filter layer, and a third-color color filter layer on a first surface that is a lower surface of the upper substrate;
a transparent layer on the first-color color filter layer, a surface of the transparent layer having a first part apart from the first surface by a first distance in a direction away from the first surface and one or more protrusions apart from the first surface by a second distance greater than the first distance in the direction away from the first surface;
a second color quantum dot layer on the second-color color filter layer;
a third color quantum dot layer on the third-color color filter layer; and
a partition between the transparent layer and the second color quantum dot layer; and
a spacer on the partition,
wherein the spacer and the transparent layer each include scattering particles.
