Abstract
(EN)
A bank (3) is provided with an opening (3K) that includes a first opening (3KA), and a second opening (3KB) diverging from the first opening (3KA) in the direction in which the second opening (3KB) overlaps a first electrode (2). At least part of the second opening (3KB) overlaps the first electrode (2). The end of the first electrode (2) on the first opening (3KA) side thereof overlaps the second opening (3KB). The maximum width (3KBW) of the second opening (3KB) is narrower than the maximum width (3KAMW) of the first opening (3KA) in a direction perpendicular to the direction in which the second opening (3KB) diverges from the first opening (3KA).

Dans la présente invention, une banque (3) est pourvue d'une ouverture (3K) qui comprend une première ouverture (3KA), et une seconde ouverture (3KB) divergeant de la première ouverture (3KA) dans la direction dans laquelle la seconde ouverture (3KB) chevauche une première électrode (2). Au moins une partie de la seconde ouverture (3KB) chevauche la première électrode (2). L'extrémité sur le côté de la première ouverture (3KA) de la première électrode (2) chevauche la seconde ouverture (3KB). La largeur maximale (3KBW) de la seconde ouverture (3KB) est plus étroite que la largeur maximale (3KAMW) de la première ouverture (3KA) dans une direction perpendiculaire à la direction dans laquelle la deuxième ouverture (3KB) diverge de la première ouverture (3KA).
