・・・・・・・(式1)
と表される。ここで、
Clc:液晶容量
Ccs:補助容量
Cgd1:自画素を選択・駆動するゲートバスラインと画素電極との間の寄生容量
Cgd2:自画素を選択・駆動しないゲートバスラインと画素電極との間の寄生容量
Csd1:自画素にドレイン電位を供給するソースバスラインと画素電極との間の寄生容量
Csd2:自画素にドレイン電位を供給しないソースバスラインと画素電極との間の寄生容量
Cetc:その他の、画素が備える容量
である。
(1)TFTの必要動作電圧範囲の拡大
(2)ゲートバスラインの入力側と終端側といったゲートバスラインGL上の位置に応じて、ゲートオフ時に変動した電位で画素電極に再書き込みする際の電位レベルが異なることに起因する、面内フリッカ特性の悪化
などが生じて、液晶表示装置の性能に悪影響を及ぼすという問題を招来する。
