Claim Text:
1. An optical film structure, comprising: a first substrate having a first surface and a second surface; an optical component having a micro-lens array disposed on the first surface of the first substrate, wherein the micro-lens array includes a plurality of micro-lens units and each of the plurality of micro-lens units has a round concentrated area with a projected radius (R) formed on the first surface; a planarization layer disposed on the optical component; and a light absorbing layer disposed on the planarization layer and having a plurality of light absorbing units, wherein each of the plurality of light absorbing units has a width (W), wherein light incident from the second surface of the first substrate passing through the micro-lens array is focused on the plurality of light absorbing units, a difference in refractive index (Δn) between the micro-lens array and the planarization layer is greater than or equal to 0.2, and the width (W) of the light absorbing unit is less than or equal to one-half of the projected radius (R/2).
