Image capturing apparatus

An image capturing apparatus comprising:

• a light guide plate having a first surface, a second surface opposite to the first surface and a plurality of third surfaces each connecting the first surface to the second surface;
• a first light transmissive layer disposed on the first surface;
• a second light transmissive layer disposed on the second surface, wherein the second light transmissive layer is overlapped with a light transfer region of the light guide plate in a normal direction of the light guide plate, and the second light transmissive layer is not overlapped with a light penetration region of the light guide plate in the normal direction;
• a third light transmissive layer disposed on the second surface and overlapped with the light transfer region and the light penetration region in the normal direction, wherein a refractive index of the third light transmissive layer is higher than a refractive index of the first light transmissive layer and a refractive index of the second light transmissive layer, and a refractive index of the light guide plate is higher than the refractive index of the first light transmissive layer and the refractive index of the second light transmissive layer;
• a light source located below the first surface or beside one of the third surfaces;
• and
• an image capturing device located below the first surface.
