Summary:The present invention provides an optical film structure, which comprises a base layer, a plurality of optical layers, and a prism layer. A first optical structure is disposed below the base layer such that the first optical structure can concentrate and alter an incident light source. By using the structure of the plurality of optical layers, the ineffective polarized light of the light source can be converted into effective polarized light. Furthermore, the first optical structure adjusts a focal point of the incident light source and thus increasing the luminous flux and brightness of the light source.
