Liquid crystal lens element, display unit and terminal

A liquid crystal lens element comprising:

• an upper substrate and a lower substrate facing each other, directions in which each of the upper substrate and the lower substrate extends being defined as a x-direction and a y-direction, the x-direction and the y-direction crossing each other, the upper substrate including a repetition area in which a plurality of A-electrode structures are arrayed in the x-direction so as to generate an electric potential gradient in the x-direction, the lower substrate including a repetition area in which a plurality of B-electrode structures are arrayed in the y-direction so as to generate an electric potential gradient in the y-direction, one of an opening section elongated in the y-direction and a central electrode elongated in the y-direction being formed in a middle of each of the plurality of A-electrode structures;
• and
• a liquid crystal layer put between the upper substrate and the lower substrate, an initial molecular orientation direction of the liquid crystal layer agreeing with the x-direction.
