Abstract

　隣り合う画素領域（５α・５β）の間隙に対応して保持容量配線（１８ｘ）が設けられ、該保持容量配線（１８ｘ）と重なるように容量電極（２７ｘａ・２７ｘｂ）が設けられ、隣り合う画素領域（５α・５γ）の間隙に対応して保持容量配線（１８ｙ）が設けられるとともに該保持容量配線（１８ｙ）と重なるように容量電極（２７ｙａ・２７ｙｂ）が設けられ、画素領域（５α）に設けられた第１の画素電極（１７ａ）は隣り合う保持容量配線（１８ｘ・１８ｙ）の一方（１８ｘ）と重なる容量電極（２７ｘａ）に電気的に接続されるとともに画素領域（５α）に設けられた第２の画素電極（１７ｂ）は他方（１８ｙ）と重なる容量電極（２７ｙｂ）に電気的に接続され、第１の画素電極（１７ａ）と容量電極（２７ｘａ）とを電気的に接続する中継配線（２７ｉａ）が設けられている。上記構成によれば、１画素に複数の画素電極を有する画素分割方式のアクティブマトリクス基板において、保持容量配線の数を抑制しつつ各画素電極の形状の自由度を高めることができる。
