Abstract
(EN) A liquid crystal display device 10 is provided with: a pixel electrode 11g; a common electrode 11h which is superimposed on the pixel electrode 11g via an interlayer insulation film 21; a plurality of touch electrodes 14 which are formed by dividing the common electrode 11h; a plurality of touch wires 15 which are selectively connected to the plurality of touch electrodes 14 and are disposed not to be superimposed on the pixel electrode 11g, with the interlayer insulation film 21 being interposed between the plurality of touch wires 15 and the common electrode 11h; and a light shielding part 11l which has a pixel opening 11l1 superimposed above the pixel electrode 11g and shields light. The common electrode 11h has an opening 24 superimposed on one of the touch wires 15. Of the opening edges in the opening 24, a first opening edge 24a which is located on the pixel electrode 11g side with respect to a corresponding one of the touch wires 15 is disposed closer to the corresponding one of the touch wires 15 than a second opening edge 24b located opposite to the pixel electrode 11g side with respect to a corresponding one of the touch wires 15.
(FR) Selon la présente invention, un dispositif d'affichage à cristaux liquides (10) comprend : une électrode de pixel (11g) ; une électrode commune (11h) qui est superposée sur l'électrode de pixel (11g) par l'intermédiaire d'un film d'isolation intercouche (21) ; une pluralité d'électrodes tactiles (14) qui sont formées par division de l'électrode commune (11h) ; une pluralité de fils tactiles (15) qui sont sélectivement connectés à la pluralité d'électrodes tactiles (14) et qui sont disposés de façon à ne pas être superposés sur l'électrode de pixel (11g), le film d'isolation inter-couche (21) étant interposé entre la pluralité de fils tactiles (15) et l'électrode commune (11h) ; et une partie de protection contre la lumière (11l) qui a une ouverture de pixel (11l1) superposée au-dessus de l'électrode de pixel (11g) et protège la lumière. L'électrode commune (11h) présente une ouverture (24) superposée sur l'un des fils tactiles (15). Des bords d'ouverture de l'ouverture (24), un premier bord d'ouverture (24a) qui est situé sur le côté de l'électrode de pixel (11g) par rapport à un fil tactile correspondant parmi les fils tactiles (15) est disposé plus près du fil tactile correspondant parmi les fils tactiles (15) que d'un second bord d'ouverture (24b) situé à l'opposé du côté de l'électrode de pixel (11g) par rapport à un fil tactile correspondant parmi les fils tactiles (15).
(JA) 液晶表示装置10は、画素電極11gと、画素電極11gに対して層間絶縁膜21を介して重畳する共通電極11hと、共通電極11hを分割してなる複数のタッチ電極14と、共通電極11hとの間に層間絶縁膜21が介在し且つ画素電極11gとは非重畳となる形で配されて複数のタッチ電極14に選択的に接続される複数のタッチ配線15と、画素電極11gと重畳する画素開口部11l1を有していて光を遮る遮光部11lと、を備え、共通電極11hは、タッチ配線15と重畳する開口部24を有していて、開口部24の開口縁のうちタッチ配線15に対して画素電極11g側に位置する第1開口縁24aが、タッチ配線15に対して画素電極11g側とは反対側に位置する第2開口縁24bよりもタッチ配線15の近くに配される。
