Light conversion substrate, display device, and method of manufacturing display device

A display device comprising a light-conversion substrate and a light-providing substrate that face each other, the light-conversion substrate and light-providing substrate including a first pixel region and a second pixel region,

• wherein the light conversion substrate comprises:
• a first substrate,
• a first light conversion pattern disposed in the first pixel region and includes first wavelength conversion particles,
• a second light conversion pattern disposed in the second pixel region and is spaced apart from the first light conversion pattern, the second light conversion pattern including second wavelength conversion particles, and
• a first scattering pattern disposed to fill a space between the first light conversion pattern and the second light conversion pattern, the first scattering pattern including scattering particles,
• wherein the light-providing substrate comprises a first emission region overlapping the first light conversion pattern, a second emission region overlapping the second light conversion pattern, and a third emission region overlapping the first scattering pattern, and
• wherein the first scattering pattern overlaps a portion of the first light conversion pattern and a portion of the second light conversion pattern in a direction of a thickness of the first substrate.

A method of manufacturing a display device, the method comprising:

• forming a first light conversion pattern on a first substrate, the first light conversion pattern including first wavelength conversion particles;
• forming a second light conversion pattern on the first substrate, wherein the second light conversion pattern is spaced apart from the first light conversion pattern and includes second wavelength conversion particles;
• and
• concurrently forming a first scattering pattern and a second scattering pattern on regions of the first substrate that are not covered by the first light conversion pattern and the second light conversion pattern, wherein the first scattering pattern and second scattering pattern overlap portions of the first light conversion pattern and second light conversion pattern in a direction of a thickness of the first substrate.
