Liquid optical element array and display

A liquid optical element array comprising:

• a first substrate and a second substrate facing each other;
• a polar liquid and a nonpolar liquid arranged between the first substrate and the second substrate and having different refractive indices;
• a barrier rib sectioning a region on the first substrate into a plurality of cell regions;
• and
• a projection arranged upright in each of the cell regions on the first substrate or the second substrate.

A display including a display section and a liquid optical element array, the liquid optical element array comprising:

• a first substrate and a second substrate facing each other;
• barrier ribs arranged upright on a surface facing the second substrate of the first substrate and sectioning a region on the first substrate into a plurality of cell regions;
• a first electrode and a second electrode arranged on wall surfaces of the barrier ribs to face each other;
• a third electrode arranged on a surface facing the first substrate of the second substrate;
• a projection arranged upright in each of the cell regions on the first substrate or the second substrate;
• and
• a polar liquid and a nonpolar liquid sealed between the first substrate and the third electrode and having different refractive indices.
