Abstract
A method of forming liquid crystal cell for a color display device includes forming a liquid crystal layer and a prism structure between top and bottom substrates. Forming the prism structure includes forming a lens shaped die, coating a low refractive index resin on the lens shaped die, pasting the lens shaped die to the top substrate, and irradiating the coated low refractive index resin so as to set the low refractive index resin and form a low refractive index layer. The lens shaped die is removed from the low refractive index layer, a high refractive index resin is coated on the low refractive index layer by use of a planarizing die. The coated high refractive index resin is irradiated so as to set the high refractive index resin and form a high refractive index layer, and the planarizing die is removed from the high refractive index layer.
