Abstract:
A method for fabricating a collimate and post diffuse type liquid crystal cell, comprising the steps of:providing a liquid crystal cell having a first substrate, and a second substrate attached to the first substrate, the first substrate having a same thickness as the second substrate, wherein the same thickness includes 0.7 mm; lapping the first substrate at a first rate; concurrently lapping the second substrate with the lapping of the first substrate, the lapping of the second substrate including a second rate different from the first rate, such that the first substrate and the second substrate are thinned to different thicknesses, wherein the different thicknesses include 0.4 nun and 0.6 mm; polishing the first and second substrates; and providing the thinner of the first and second substrates on a viewer side of the collimate and post diffuse type liquid crystal cell to reduce depixelization.
