Description
Claims (6)
- 表側に位置する基板と、裏側に位置する基板と、両基板の間に保持された液晶とから成るパネルを備え、
該パネルは、裏側から入射した照明光を変調して表側に出射する開口部と、表側から入射した外光を不要に反射する金属配線を含む反射部とを有し、
該パネルの表側に位相差板が配されており、該位相差板と該反射部に位置する液晶とを合わせてリタデーションが外光の波長の1/4に近づく様に調整されており、且つ、該パネルの表側に偏光板が配されており、外光を直線偏光にして該反射部に入射させ、リタデーションによって90度回転して戻ってきた直線偏光を吸収し、以て、該反射部による外光の不要反射を抑制することを特徴とする液晶表示装置。 - 前記パネルの裏側にも位相差板が配されており、表裏一対の位相差板と両者の間に位置する液晶とを合わせた前記開口部のリタデーションが照明光の波長の1/2に近づく様に調整されていることを特徴とする請求項1に記載の液晶表示装置。
- 前記一対の位相差板はその遅相軸が互いに直交する様に配されているとともに、前記液晶の配向方向が片方の位相差板の遅相軸と一致していることを特徴とする請求項2に記載の液晶表示装置。
- 前記一対の位相差板の少なくとも一方は前記液晶の厚み方向であるZ軸にも位相差を有することを特徴とする請求項2に記載の液晶表示装置。
- 前記位相差板は液晶材料をハイブリッド配向してZ軸にも位相差をもたせたものであることを特徴とする請求項4に記載の液晶表示装置。
- 前記液晶はその配向方向が前記パネルの主視角方向からずれていることを特徴とする請求項1に記載の液晶表示装置。
