Provided is a method for controlling liquid crystal alignment. An alignment film has a plurality of first grooves which are elongated in a first direction and area spaced from each other, and a plurality of second grooves which are elongated in a second direction and are spaced from each other by crossing said first grooves. Multistable liquid crystal alignment is enabled selectively by adjusting an aspect ratio of said first grooves and an aspect ratio of said second grooves.
