Patent ID: 8879016

Claim:
A method of forming liquid crystal cell for a color display device, the method comprising: forming a liquid crystal layer and a prism structure between top and bottom substrates, the liquid crystal layer including thin film transistors (TFT) formed therein, wherein forming the prism structure further comprises: forming a lens shaped die from a first die material; coating a low refractive index photo-setting resin on the lens shaped die; pasting the lens shaped die to the top substrate; irradiating the coated low refractive index photo-setting resin so as to set the low refractive index resin on a surface of the top substrate and form a low refractive index layer; removing the lens shaped die from the low refractive index layer set on the top substrate; coating a high refractive index photo-setting resin on the low refractive index layer by use of a planarizing die; irradiating the coated high refractive index photo-setting resin so as to set the high refractive index resin and form a high refractive index layer; and removing the planarizing die from the high refractive index layer set on the low refractive index layer; wherein the first die material comprises one of: a metal material and a silicon elastomer material.
