Abstract
(EN)
A display substrate and a display device. The display substrate comprises an alignment film (12) and multiple rows of pixel units (20) arranged in a first direction (X). Each row of pixel units (20) comprises a plurality of pixel units (20) arranged in a second direction (Y), and the second direction (Y) intersects with the first direction (X). The included angle (θ) between a rubbing direction (B) of the alignment film (12) and the first direction (X) is an acute angle. The rubbing direction of the alignment film of the display substrate is configured to form an acute angle with respect to the first direction, thereby changing the contrast ratio of the display device viewed from a specific direction.

L'invention concerne un substrat d’affichage et un dispositif d’affichage. Le substrat d'affichage comprend un film d'alignement (12) et de multiples rangées d'unités de pixels (20) agencées dans une première direction (X). Chaque rangée d'unités de pixels (20) comprend une pluralité d'unités de pixels (20) agencées dans une seconde direction (Y), et la seconde direction (Y) croise la première direction (X). L'angle inclus (θ) entre une direction de frottement (B) du film d'alignement (12) et la première direction (X) est un angle aigu. La direction de frottement du film d'alignement du substrat d'affichage est configurée pour former un angle aigu par rapport à la première direction, ce qui permet de modifier le rapport de contraste du dispositif d'affichage vu d'une direction spécifique.
