A novel transflective liquid crystal display is demonstrated by using cholesteric liquid crystal as a LC layer and an image-enhanced reflector (IER) on the top of the transmissive sub-pixel, providing the similar paths for both reflected and transmitted light, and two circular polarizers laminated on the upper and rear substrates. An extended IER (EIER) is applied to enhance the brightness and CR. As a result, Ch-LCD displays the same image color in any ambience, thus greatly improve the image quality of the transflective cholesteric LCD.

A transflective cholesteric liquid crystal display (ChLCD) is demonstrated by using the image-enhanced reflector (IER) film on the top of the transmissive region to provide the similar paths for both transmissive and reflective light, thus, to display same image color in any ambience, improving the image quality. For full color display, the inkjet printing was applied and the patterned Ch-LC droplet was successfully deposited on the substrate. Thus, full-color Ch-LCD can be fabricated by IJP.
