Recently, the display device was developed to apply to the transparency display device(TDD), but the TDD was no brightness. The purpose of this paper was introduced a double layer optical film to improve luminance of the TDD. The film was doped micro metal oxide particles to increase the effect of scattering and refraction, and the micro structure was fabricated between the top and bottom film to enhance the light into the TDD. This research provided a transparent double layer optical film. The transparency of the film was achieved to 70 %, and the brightness efficiency up to 60 %.
