Abstract: An optical sensing device and a method for manufacturing the same are provided. The optical sensing device comprises a substrate, an optical acting area, a filter layer and a carbonized sidewall. The optical acting area is disposed on the substrate. The filter layer covers the optical acting area and selectively allows only a light beam with a specific wavelength to pass therethrough and be received by the optical acting area while blocking the light beams with other wavelengths. The carbonized sidewall covers the sidewall of the filter layer and a portion of the sidewall of the substrate to prevent the light beams with the other wavelengths from being received by the optical acting area through the sidewall of the substrate.
