Imaging lens assembly module and electronic device

An imaging lens assembly module, comprising:

• an image sensor comprising a micro lens layer;
• a light transmitting element disposed above the micro lens layer, a gap formed between the light transmitting element and the micro lens layer, a light passing through the light transmitting element and then traveling into the image sensor, and the light transmitting element comprising:
• a lower surface facing the micro lens layer;
• and
• an upper surface opposing the lower surface;
• at least one anti-reflection coating disposed on at least one of the upper surface and the lower surface of the light transmitting element and the micro lens layer, wherein the at least one anti-reflection coating comprises a plurality of high refractive index layers and a plurality of low refractive index layers alternately stacked;
• and
• at least one anti-reflection structure disposed on at least one of the upper surface and the lower surface of the light transmitting element and the micro lens layer, wherein the at least one anti-reflection structure comprises a plurality of ridge-like protrusions non-directionally extending from a disposing surface, a bottom of each of the ridge-like protrusions is closer to the disposing surface than a top of each of the ridge-like protrusions to the disposing surface, and the ridge-like protrusions are tapered from the bottom to the top.
