Electronic device and sensor package with optical functional layer thereof

A sensor package, comprising:

• a substrate;
• a light sensor disposed on the substrate, wherein the light sensor has a light receiving region, and receives light through the light receiving region;
• at least one optical filter disposed on the light sensor and covering the light receiving region;
• and
• an optical functional layer being light-permeable and including a plurality of light-scattering particles, wherein the optical functional layer is disposed on the substrate, and covers the light sensor and the at least one optical filter;
• wherein, when external light passes through the at least one optical filter within an incident angle range and is received by the light receiving region of the light sensor, the light sensor responds to a specific wavelength range of the external light, and a response spectrum is obtained;
• wherein, within the incident angle range, an absolute value of an offset measured at a crest of a waveform of the response spectrum is less than or equal to 10 nm.
