Abstract
Provided are a method for manufacturing a liquid crystal lens which, even with the use of a thin sheet glass as a glass sheet for dividing a liquid crystal layer, can reduce the likelihood of breakage of the thin sheet glass in the production process and the liquid crystal lens. A mother liquid crystal lens having a plurality of liquid crystal lens units arrayed in a longitudinal direction thereof is cut for each of the liquid crystal lens units to separate out the liquid crystal lens units and thus manufacture respective liquid crystal lenses 10. Longitudinally extending side surfaces 13c, 13d, 14c, and 14d of glass ribbons which provide thin sheet glasses 13 and 14 have an outwardly bulging curved shape in a cross section perpendicular to the longitudinal direction.
