Abstract:
(EN) Provided is a liquid crystal display device that can improve visual angle characteristics. The liquid crystal display device comprises: a first switching element (11) that is connected at one controlled terminal to a pixel electrode (12) of a first subpixel (10); a second switching element (21) that is connected at one controlled terminal to a pixel electrode (22) of a second subpixel (20); a first drive line (1) that is connected to the other controlled terminal of the first switching element (11); a second drive line (2) that is connected to the other controlled terminal of the second switching element (21); a gradation signal line (4) that is connected to a counter electrode (13) of the first subpixel (10) and to a counter electrode (23) of the second subpixel; and a scanning line (3) that is connected to the control terminals of the first switching element (11) and the second switching element (21). A first drive signal in which the polarity is inverted is applied to the first drive line (1), and a second drive signal having a different polarity than that of the first drive signal is applied to the second drive line (2).
(FR) L'invention concerne un dispositif d'affichage à cristaux liquides qui peut améliorer des caractéristiques d'angle visuel. Le dispositif d'affichage à cristaux liquides comprend : un premier élément de commutation (11) qui est connecté sur une borne commandée à une électrode de pixel (12) d'un premier sous-pixel (10) ; un second élément de commutation (21) qui est connecté sur une borne commandée à une électrode de pixel (22) d'un second sous-pixel (20) ; une première ligne d'attaque (1) qui est connectée à l'autre borne commandée du premier élément de commutation (11) ; une seconde ligne d'attaque (2) qui est connectée à l'autre borne commandée du second élément de commutation (21) ; une ligne de signal de gradation (4) qui est connectée à une contre-électrode (13) du premier sous-pixel (10) et à une contre-électrode (23) du second sous-pixel ; et une ligne de balayage (3) qui est connectée aux bornes de commande du premier élément de commutation (11) et du second élément de commutation (21). Un premier signal d'attaque dans lequel la polarité est inversée est appliqué à la première ligne d'attaque (1), et un second signal d'attaque ayant une polarité différente de celle du premier signal d'attaque est appliqué à la seconde ligne d'attaque (2).
(JA) 視野角特性を改善することができる液晶表示装置を提供する。 液晶表示装置は、第1副画素(10)の画素電極(12)に被制御端子の一方を接続した第1スイッチング素子(11)と、第2副画素(20)の画素電極(22)に被制御端子の一方を接続した第2スイッチング素子(21)と、第1スイッチング素子(11)の他方の被制御端子に接続した第1駆動線(1)と、第2スイッチング素子(21)の他方の被制御端子に接続した第2駆動線(2)と、第1副画素(10)の対向電極(13)及び第2副画素の対向電極(23)それぞれに接続した階調信号線(4)と、第1スイッチング素子(11)及び第2スイッチング素子(21)それぞれの制御端子に接続した走査線(3)とを備え、第1駆動線(1)に極性が反転する第1駆動信号を印加し、第2駆動線(2)に第1駆動信号の極性と異なる極性の第2駆動信号を印加する。
