<p><P>PROBLEM TO BE SOLVED: To provide a lens array element and an image display device easily switching the direction of a lens effect of a cylindrical lens between two directions. <P>SOLUTION: A first electrode group 14 and a second electrode group 24 are arranged face to face via a liquid crystal layer 3, and the first electrode group 14 and the second electrode group 24 are constructed of a plurality of transparent electrodes extending in two different directions. By properly controlling states of voltages applied to the first electrode group 14 and the second electrode group 24, a lens effect on the liquid crystal layer 3 is controlled properly. The liquid crystal layer 3 is electrically switched in three states: a state with no lens effect; a first lens state where a lens effect of a first cylindrical lens extending in the first direction is produced; and a second lens state where a lens effect of a second cylindrical lens extending in the second direction is produced. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
