Optical lens assembly and electronic device

An optical lens assembly, comprising:

• a lens barrel comprising a light entering hole, which is configured for allowing a light to enter the lens barrel;
• and
• an optical lens group, wherein the lens barrel accommodates the optical lens group, and an optical axis passes through the optical lens group;
• wherein the optical lens group comprises:
• a plurality of lens elements;
• and
• at least one light blocking sheet being an opaque sheet-shaped element and surrounding the optical axis to form a light passing hole, wherein the light blocking sheet comprises an object-side surface and an image-side surface, the object-side surface is located more adjacent to the light entering hole than the image-side surface thereto, and a first film layer is disposed on the object-side surface;
• wherein a reflected light is obtained from the first film layer irradiated by a standard illuminant D65, a color index of the reflected light is defined according to a CIE 1976 L*a*b* color space, the color index is CI, the reflected light has a maximum reflectivity in a spectrum in a wavelength range of 380 nm to 780 nm, a wavelength range of a wavelength corresponding to the maximum reflectivity minus 50 nm to the wavelength thereto plus 50 nm is a high reflectivity section, a wavelength range remained in a wavelength range of 380 nm to 780 nm excluding the high reflectivity section is a second reflectivity section, an average reflectivity in the high reflectivity section is Rhigh, an average reflectivity in the second reflectivity section is R2, and the following conditions are satisfied:
• CI={(L*)×[(a*)2+(b*)2]}1/2;
• 8≤CI≤41;
• and
• 1.8≤RhighR2≤6.2.
