Abstract
(EN)
The present invention provides a liquid crystal display device and a liquid crystal display panel wherein it is possible to sufficiently widen the view angle and to sufficiently increase transmittance. The liquid crystal display panel of the present invention contains a pair of substrates and a liquid crystal layer encapsulated between the pair of substrates, wherein: with regard to the pair of substrates, subpixel electrodes are disposed on at least one of the substrates and common electrodes are disposed on the same substrate as the aforementioned substrate or the other substrate; when viewing the main surface of the substrate in planar view, the subpixel electrodes and the common electrodes have a perpendicularly bent section and two positions of the electrodes extending in the longitudinal direction from the bent section are disposed parallel to one another; and, for every subpixel, there are four or fewer bent sections of the electrodes.

L'invention concerne un dispositif d'affichage à cristaux liquides et un panneau d'affichage à cristaux liquides qui permettent d'élargir suffisamment l'angle de vue et d'augmenter suffisamment la transmittance. Le panneau d'affichage à cristaux liquides comprend deux substrats et une couche de cristaux liquides encapsulée entre les deux substrats. En ce qui concerne les deux substrats, des électrodes de sous-pixels sont disposées sur au moins un des substrats, et des électrodes communes sont disposées sur le même substrat que le substrat susmentionné ou sur l'autre substrat. Lorsque l'on regarde la surface principale du substrat selon une vue en plan, les électrodes de sous-pixels et les électrodes communes ont une section courbée perpendiculairement et deux positions des électrodes s'étendant dans le sens longitudinal depuis la section courbe sont disposées en parallèle l'une à l'autre. Pour chaque sous-pixel, les électrodes comportent quatre sections courbes ou moins.
