本論文提出一種不同以往黃光製程的方法來製作液晶透鏡元件。由於光致導電高分子聚乙烯咔唑 (PVK) 的導電性隨紫外光照射程度而有所差異之特性，我們利用漸進式光罩產生導電性的漸進式變化以達成電場強度的梯度分佈。因此液晶分子的長軸會隨著電場梯度分佈而重新排列，造成入射光隨液晶分子排列方向而感受到不同折射率，即折射率隨著電場產生梯度分佈。再利用藍相液晶擁有光學各向同性之特性，使得基板不需要配向處理，因此在反應時間變短與製程縮減上有突出的表現，如此可形成一種具有快速反應與無偏振依賴性的液晶透鏡元件。

The new approach is proposed to fabricate the liquid crystals lens without the traditional lithography process. Owing to the characteristics of photo-induced conducting polymer polyvinylcarbazole (PVK), which the conductivity depends on the irradiation of UV light, a progressive mask resulting in the variation of conductivity is adopted to produce the gradient distribution of electric field. The reorientation of liquid crystals according to the gradient distribution of electric field induces the variation of refractive index. Therefore, the incident light will experience the gradient distribution of refractive index. The optically isotropic feature of blue phase liquid crystals has been employed to the device of micro-lens arrays without the alignment layer. Because the response time will be shortened and the process will be reduced, this new fabrication of liquid crystals lens possesses the characteristics of fast response and polarization independence.
