Resumen

The invention describes liquid crystal microlens (1), comprising: an upper substrate (2s) and a lower substrate (2i); an upper alignment layer (3s) and a lower alignment layer (3i); and a liquid crystal layer (4) between the upper alignment layer (3s) and the lower alignment layer (3i), wherein: the upper substrate (2s) comprises control electrodes (51, 52) and the substrate (2i) ) lower comprises control electrodes (53, 54), said electrodes (51, 52, 53, 54) forming a flat figure, and where each electrode (51, 52, 53, 54) is excited by an alternating electrical signal, being 180º out of phase the electrical signals of the electrodes (51, 52, 53, 54) of the same substrate (2s, 2i), and the electrical signals of the electrodes (51, 52) of the upper substrate (2s) being offset by 90º to the electrical signals of the electrodes (53, 54) of the lower substrate (2i).
