Abstract
An image sensing device includes a substrate, a light sensing circuit disposed on the substrate, an optical film. The optical film includes a transparent film having a first light transmittance value wherein the first light transmittance value includes a red light transmittance value and a blue light transmittance value, and the red light transmittance value is greater than the blue light transmittance value; and a grating structure having a second light transmittance value, wherein the first light transmittance value is greater than the second light transmittance value. The substrate is sandwiched between the light sensing circuit and the optional film, and a light source disposed on the optical film, wherein the optical film is sandwiched between the substrate and the light source.
