Claim 17:
18. A color conversion substrate, comprising:
a base substrate including a first light transmitting region, a second light transmitting region separated from the first light transmitting region in a first direction, and a first light blocking region between the first light transmitting region and the second light transmitting region;
a first color filter disposed on a surface of the base substrate to overlap the first light transmitting region;
a second color filter disposed on the surface of the base substrate to overlap the second light transmitting region;
a capping layer disposed on the first color filter, the second color filter and the surface of the base substrate;
a partition wall overlapping the first light blocking region and disposed on the capping layer; and
a first wavelength conversion pattern disposed on the first color filter and a second wavelength conversion pattern disposed on the second color filter,
wherein the partition wall includes a first partition layer disposed on the first color filter and the second color filter and a second partition layer disposed on the first partition layer,
the second partition layer overlaps at least a portion of the first color filter and the second color filter, and is spaced apart from the first color filter and the second color filter,
the first partition layer includes a first lower surface disposed on the first color filter and a second lower surface disposed on the second color filter,
an upper surface of the first partition layer is greater than a lower surface of the second partition layer,
the lower surface of the capping layer is in direct contact with the first color first and the second color filter, and
the upper surface of the capping layer is in direct contact with the first and second lower surfaces of the first partition layer.
