I bet you could get a lot better color if you used the screen itself to generate the bayer pattern on film rather than printing it with a printer.

Get some large format color negative film and thin cyan, magenta, and yellow filters. Put a cyan filter on the LCD, followed by the film on top. In a darkroom, light up the "red" pixels and to expose that part of the film. Repeat with the magenta filter and "green" pixels, and finally the yellow filter and "blue" pixels. Develop the film and reattach to the LCD.

This is kind of how the shadow mask was made in color CRT monitors. A photographic process was used to put the red, green, and blue phosphor dots on the screen by shining light through the shadow mask from the same angles the electron guns would later illuminate the phosphors. This ensures that the red, green, and blue phosphor dot pattern lines up (fairly) accurately with the shadow mask.
