In this paper, a liquid lenticular lens with correct focal length was designed by controlling the width of the electrode and analyzing the microfluidic phenomena at boundary between oil and salted water in the liquid lenticular lens. A liquid lenticular lens that has inaccurate focal length results in serious crosstalk and three-dimensional (3-D) image distortion. Therefore, to reduce the crosstalk, the liquid lenticular lens should be fabricated in such a way that the image plane of the LCD is at the focal plane of the lens. To do so, the width of the electrode was adjusted and saturation angle between two liquids and the sidewall of the chamber was measured. The optimum width of the electrode was derived by applying the saturation angle and a final sample having a short focal length was fabricated. When the width of the electrode was optimized, the crosstalk was measured at 21.95% and the value was 10% less than when not being optimized. Also, the viewing angle was increased up to 45&#x00B0;. As a result, this crosstalk reduction led to 3-D image enhancement.
