Abstract: An optical film structure includes a first substrate having a first surface and a second surface, an optical component includes a micro-lens array and disposed on the first surface of the first substrate, a micro-lens array including a plurality of micro-lens units each of which has a round concentrated area with a projected radius R formed on the first surface, a planarization layer disposed on the optical component, a light absorbing layer disposed on the planarization layer and including a plurality of light absorbing units each of which has a width W. Light incident from the second surface of the first substrate and passing through the micro-lens array is focused on the light absorbing units. The micro-lens array and the planarization layer have a difference in refractive index greater than or equal to 0.2; and W is less than or equal to R/2.
