Color conversion substrate and display apparatus

A color conversion substrate, comprising:

• a base substrate;
• and
• a color conversion layer and a second light scattering layer on the base substrate;
• wherein the color conversion substrate comprises a plurality of subpixels;
• the plurality of subpixels comprise a first subpixel, a second subpixel, and a third subpixel;
• the color conversion substrate has a first light transmissive region in the first subpixel, a second light transmissive region in the second subpixel, a third light transmissive region in the third subpixel, and a light non-transmissive region;
• the color conversion layer comprises a plurality of color conversion blocks;
• the second light scattering layer comprises a plurality of light scattering blocks;
• the plurality of color conversion blocks comprise a first color conversion block and a second color conversion block;
• the first color conversion block is at least partially in the first subpixel;
• the second color conversion block is at least partially in the second subpixel;
• a light scattering block of the plurality of light scattering blocks is at least partially in the third subpixel;
• and
• at least one of a thickness of at least a portion of the first color conversion block along a direction perpendicular to the base substrate or a thickness of at least a portion of the second color conversion block along the direction perpendicular to the base substrate is greater than a thickness of at least a portion of the light scattering block along the direction perpendicular to the base substrate.
