Abstract
液晶デイスプレイパネルの蓄電量を高めることができる薄膜トランジスタ列を提供すること。
【解決手段】
画素の蓄電量を供給する複数の共通ラインを備える薄膜トランジスタ列が提供される。特に、これら共通ラインのそれぞれは、複数の分岐部を備えている。共通ライン、その分岐部および画素電極は、蓄電器を構成する。分岐部は、輝度品質が悪い画素に配置される。このため、画素の口径比を変えることなく、画素の蓄電量を高めることができる。従って、液晶ディスプレイパネルの性能を改善することができる。
【選択図】 図3
Description
一般に、高い口径比(アパーチュアレシオ)が良好な輝度品質をもたらす。他の面において、蓄電器Cstの蓄電量(キャパシタンス)を大きくすると、液晶ディスプレイの光電効率が良好になる。
