Description
図1Aは、実施の形態に係る画像表示装置1の概略断面図であり、図1Bは、図1Aに示す画像表示装置1の一部の分解斜視図である。尚、図1Aにおいては、図1Bに記載の電極40a、40b、41a、41bの記載が省略されている。
更に、プリズム17の表面上及び電極40a及び40b上には、液晶分子の配向方向を所望の方向に制御するための配向処理を施した配向膜18及び19が設けられている。配向膜18及び19は、電極40a、40b、41a、41bに電圧が印加されていない状態で、液晶分子の長軸がY軸方向となるように液晶分子を配向させる。ただし、液晶分子の配向が均一に保てるのであれば、配向膜18及び19はなくても良い。
本発明に係る液晶プリズム素子の最適な設計の説明に先だって、まず、比較例に係る液晶プリズム素子の構成を説明する。以下の説明の設定条件として、視聴者と画像表示装置との垂直距離(図1Aのh)を300mmとし、画像表示パネル4の幅(図1Aのw)を221mm、液晶材料の異常光屈折率neを1.737とし、常光屈折率noを1.537(Δn=0.2)とし、プリズムの屈折率nを1.6とした。また、上述の条件では、バックライト2から出射され、画面中央にいる視聴者に向かう光線が液晶プリズム素子に入射する光線角度は、画面中央では0°、画面右端では20.2°となる。
図2は、比較例に係る液晶プリズム素子の構成を示す概略図である。より詳細には、図2(a)は、画面中央に配置されるプリズムの断面形状を示し、図2(b)は、画面右端に配置されるプリズムの断面形状を示す。
図4は、実施例1に係る液晶プリズム素子における光のケラレを説明する図である。
図5は、実施例2に係る液晶プリズム素子における光のケラレを説明する図である。
