AI Technical Summary
Technical Problem
Current reflective liquid crystal display (RLCD) technologies suffer from reduced optical efficiency due to the black matrix blocking light leakage, leading to narrow viewing angles and poor color reproduction.
Method used
A color filter with multiple convex or concave light-expanding structures on photoresist blocks that scatter incident light, increasing the viewing angle by changing the direction of light travel.
Benefits of technology
Improves the viewing angle and maintains color reproduction by enhancing light scattering, addressing the limitations of conventional RLCDs.

Abstract
The present disclosure provides a color filter including a substrate and a color filter layer. The substrate has a first surface and a second surface opposite to each other. The color filter layer is formed on the first surface of the substrate and includes a plurality of photoresist blocks, wherein each photoresist block has a plurality of light diffusion structures on a surface facing away from the substrate. A reflective display including the color filter is also provided.
