Abstract:
A method of fabricating a polarized color filter wherein a transparent substrate is provided and coated with a photoresist layer. A wave-shaped mask may then be prepared and a periodic wave-shaped surface may be placed in contact with the photoresist layer, treating the photoresist layer with a primary exposure process. An external force may be applied to the wave-shaped mask, and the transparent substrate or wave-shaped mask by be rotated by a predetermined degree. The photoresist layer may be treated with a secondary exposure process, wherein the photoresist layer is developed in order to obtain a photoresist pattern layer. A metal layer may be coated on the transparent substrate with the photoresist pattern layer. The photoresist pattern layer and the portion of the metal layer on the photoresist pattern layer may then be removed such that the remaining metal layer forms a periodic hole substrate.
