The liquid crystal display device adopts a cholesteric liquid crystal color filter. Each portion of the cholesteric liquid crystal color filter is designed to have an adjusted order parameter according to a wavelength of a corresponding color ray. Therefore, with the variously adjusted order parameters of the cholesteric liquid crystal color filter, an increase of the color shift due to a longer wavelength is prevented.

The transflective liquid crystal panel includes the pixel electrode having the transparent electrode and reflective electrode and the reflective film having the transmitting hole. Therefore, the light generated from the backlight device can pass through the transmitting hole and transparent electrode into the liquid crystal. Moreover, the light reflected in the reflective film can also pass through them into the liquid crystal without being absorbed by the lower polarizer. That is, the brightness of the transflective LCD device is improved.

Abstract: A method of forming a photoresist pattern having a uniformly fine line width, and a method of manufacturing a semiconductor device using such a photoresist pattern as a mask, include the step of forming an anti-reflective coating (ARC) using only a hydrocarbon based gas. A highly reflective layer is formed on a semiconductor substrate on which an underlayer is disposed. Using only a hydrocarbon based gas, the ARC is formed on the highly reflective layer. A photoresist layer is formed on the ARC, and is exposed and developed to form a photoresist pattern on the ARC. The ARC and the highly reflective layer under the photoresist pattern are etched using the photoresist pattern as a mask. Thereafter, the photoresist pattern and the ARC are simultaneously removed. The ARC is of an amorphous silicon film having high etching selectivity and being easily removed along with the photoresist pattern.
