Claim Text:
1. 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; an opening section elongated in the y-direction and being formed in a middle of each of the plurality of A-electrode structures in the x-direction; and a liquid crystal layer between the upper substrate and the lower substrate, an initial molecular orientation direction of the liquid crystal layer agreeing with the x-direction, wherein each of the plurality of A-electrode structures includes a first conductive layer, a first insulating layer, stripe structures formed of a second conductive layer, a second insulating layer and a resistive layer, which are layered on the upper substrate, the first conductive layers of the plurality of A-electrode structures form an electrode covering an entire of the upper substrate, the stripe structures extend in the y-direction, and the resistive layer has a sheet resistance whose value is between a value of a sheet resistance of the first conductive layer or the second conductive layer and a value of a sheet resistance of the second insulating layer.
