1. A color converting substrate comprising:
a base portion having, defined thereon, a first light transmission area, a first light blocking area, and a second light transmission area, which are sequentially arranged along a first direction;
a first wavelength converting pattern positioned on the base portion and configured to wavelength-convert light of a first color into light of a second color;
a second wavelength converting pattern positioned on the base portion and configured to wavelength-convert the light of the first color into light of a third color; and
a light transmission pattern positioned on the base portion and configured to transmit the light of the first color therethrough,
wherein
one of the first wavelength converting pattern, the second wavelength converting pattern, and the light transmission pattern is disposed in the first light-blocking area,
another one of the first wavelength converting pattern, the second wavelength converting pattern, and the light transmission pattern is disposed in the first light transmission area,
yet another one of the first wavelength converting pattern, the second wavelength converting pattern, and the light transmission pattern is disposed in the second light transmission area,
a third light transmission area, which is spaced apart, along the first direction, from the first light blocking area with the first light transmission area interposed therebetween, is further defined on the base portion, and
the first wavelength converting pattern is disposed in the third light transmission area of the base portion.
