Claims (1)
- 対向配置された第1の基板と第2の基板の間に負の誘電率異方性を有する液晶が封入され、
前記第1の基板となる一方の支持基板の対向面側に行列状に配列された複数の薄膜トランジスタと、これら薄膜トランジスタに接続され互いに交差するゲートラインおよびドレインラインと、前記複数の薄膜トランジスタ、ゲートラインおよびドレインラインを覆う絶縁膜と、該絶縁膜上に形成され前記絶縁膜に開けられた開口部を介して前記薄膜トランジスタの個々に対応して接続された液晶駆動用の複数の画素電極と、これら画素電極上に形成されたラビング処理が施されていない垂直配向膜と、前記第2の基板となる他方の支持基板の対向面に形成された液晶駆動用の共通電極と、該共通電極中の前記画素電極に対向する領域内に設けられた前記液晶の配向方向を制御する配向制御手段と、前記共通電極上に形成されたラビング処理が施されていない垂直配向膜と、を有し、
前記第1の基板および前記第2の基板の外側面には偏光板が設けられてなり、該偏光板を抜けた偏光を前記液晶にて変調することにより表示を行う液晶表示装置において、
前記絶縁膜は少なくとも該絶縁膜に開けられた前記開口部を除く前記薄膜トランジスタ上の表面が実質的に平坦化され、
前記液晶の初期配向方向を前記基板の概ね法線方向として黒表示を行い、
前記画素電極と前記共通電極との間に電圧を印加することによって前記画素電極周辺と共通電極間に斜め方向電界を発生させ、前記液晶を概ね法線方向より前記斜め方向電界に従って傾斜させて前記液晶の配向方向を隣接する前記画素電極間で分割すると共に、前記配向制御手段により1画素内での前記液晶の配向方向を画素分割し、前記配向制御手段、前記画素電極および前記薄膜トランジスタを前記第1の基板の法線方向に重畳させることを特徴とする液晶表示装置。
