本研究主要目標為探討硬式與軟式高分子材質導光板的設計與製程，其目的為改善現有導光板技術的品質與降低成本。在硬式導光板部份，重點在於導光板上表面的微結構UV-LIGA like製程。從黃光微影到電鍍翻模，最後以熱壓方式製作出效率比市售產品好之硬式壓克力導光板，探討導光板表面微結構對於光學性質之影響。經過最佳化製程後，導光板使用一片擴散膜與兩片交錯增亮膜的出光均齊度約75 % ~ 83 %，相當於市售參考組均齊度79 %的數值，而整體出光亮度相較於同樣量測條件市售參考組亦高出3 ~ 6 %。
在軟式導光板部分，利用雷射加工技術來製作模具，再利用PDMS澆鑄技術製作出高均齊度與高效率的可撓式導光板。將分別探討雷射功率與加工間距參數對基板影響，另外也探討PDMS的表面微結構形貌，最後將不同微結構形貌與間距對於導光板的出光均勻度進行光學性質分析。完成之PDMS導光板在未使用任何光學膜片之前均齊度即高達74 %，成品具有可撓的特性，可運用在未來軟式顯示器的背光源或是軟性光源之用途。

The aim of this research is investigating the design and fabrication of hard and soft light guide plates to improve the quality of commercial product made by present technology and reduce the cost. In the part of hard light guide plates, the key point is the microstructures on the light guide plates made by UV-LIGA formation. UV-LIGA fabrication process has been followed from lithography process to electroforming process and embossing process to get the better guide light plates than commercial products. Afterwards, the influences of microstructures and optical properties are discussed. The uniformity of light guide plates which covered one diffusive sheet and two crossed brightness enhance films is around 75 % ~ 83 %, and the luminance is higher than commercial products 3 ~ 6 % at the same measurement condition.
In the part of soft light guide plates, PMMA molds are manufactured by CO2 laser process. PDMS is poured into the mold to get the flexible light guide plates which have high uniformity and luminance. Then the effects of laser powers and pitches on soft light guide plate are discussed and also the optical properties of various PDMS microstructures and pitches are analyzed. Finally, the uniformity of the best flexible PDMS light guide plate is 74 %, and it can apply to flexible display or light source.
