SWITCHABLE LENS DEVICE, METHOD OF MANUFACTURING THE SAME, AND 2-DIMENSIONAL AND 3-DIMENSIONAL IMAGE DISPLAY DEVICE USING THE SAME

摘要

A switchable lens device, a method of manufacturing the same, and a 2-dimensional (2D) and 3-dimensional (3D) image display device using the same are disclosed. The switchable lens device includes a first base film, a first lens layer which is formed on the first base film, has a first refractive index in a first direction, has a second refractive index less than the first refractive index in a second direction vertical to the first direction, and has concave surfaces, a second lens layer which has convex surfaces filled in the concave surfaces of the first lens layer and has the first refractive index, and a second base film attached to the second lens layer.
