Color converter layer and manufacturing method thereof

A color converter layer comprising:

• a first light blocking member in which a plurality of pixel regions comprising a first pixel region and a second pixel region are disposed to be spaced apart from each other;
• a first color converter disposed in the first pixel region and configured to convert incident light into a first color and emit the incident light in the first color;
• a second color converter disposed in the second pixel region and configured to:
• convert the incident light into a second color that is different from the first color, and
• emit the incident light in the second color;
• and
• a second light blocking member that extends with a preset thickness and is formed on a surface of the first light blocking member, and is configured to block transmission of the incident light into an adjacent pixel region by partitioning the first pixel region and the second pixel region,
• wherein the preset thickness of the second light blocking member is greater than a thickness of the first light blocking member,
• wherein the second light blocking member comprises a first region and a second region,
• wherein the first region and the second region are configured to support a lateral portion in a row direction and a column direction of optical resin,
• wherein the first region is thicker than the second region in a direction extending downward toward the first light blocking member, and
• wherein the optical resin surrounds each of a plurality of light sources with a structure in which an upper surface is curved and configured to guide incident light emitted from the plurality of light sources in a direction of the first color converter or the second color converter.
