A liquid crystal display cell having improved cell gap uniformity is made by depositing a plurality of spacer particles on the cell substrate then subjecting the substrate to an external energy source to selectively dislodge and remove the larger particles, such as by immersing the substrate in and ultrasonic bath. Because the larger particles will inherently have a lesser attraction to the substrate relative to their mass, subjecting the entire substrate to the ultrasonic bath will inherently preferentially remove the larger particles, resulting in a distribution having a smaller standard deviation than the initial mixture of particles deposited on the substrate as well as an asymmetric reduction in the number of gap-dominating large particles.
