Abstract

　１つの画素列に対応して設けられる第１および第２データ信号線（Ｓ１・ｓ１）を備え、画素（Ｐ）には同一の走査信号線（例えば、Ｇ１）に接続された４個の副画素（１ａ～１ｄ）が含まれるとともに、画素（Ｐ）に２本の保持容量配線（Ｃｓ１・Ｃｓ２）が対応し、画素（Ｐ）の２個の副画素（１ａ・１ｃ）が上記２本の保持容量配線の一方（Ｃｓ１）と容量を形成するとともに、これら副画素の一方（１ａ）が第１データ信号線（Ｓ１）に接続され、かつ他方（１ｃ）が第２データ信号線（ｓ１）に接続されており、残る２個の副画素（１ｂ・１ｄ）が上記２本の保持容量配線の他方（Ｃｓ２）と容量を形成するとともに、これら副画素の一方（１ｂ）が第１データ信号線（Ｓ１）に接続され、かつ他方（１ｄ）が第２データ信号線（ｓ１）に接続されている。上記構成によれば、１画素に設けた４つの副画素を異なる輝度に制御し、これによって中間調を表示することが可能となる。
