Abstract
A diffuser and an Indication panel are provided. The diffuser includes: a plurality of light-transmitting regions; and a light-shielding region located between adjacent ones of the plurality of light-transmitting regions, and each of the light-transmitting regions corresponds to an icon symbol on the indication panel. The diffuser is employed to avoid a phenomenon of light leakage between adjacent icon symbols, thereby improving the display effect of the indication panel.
