Abstract: A reflective cholesteric liquid crystal color filter is provided to obtain a constant pitch regardless of viewing angles by forming hemispheric shapes on a lower substrate coated with cholesteric liquid crystal. A reflective cholesteric liquid crystal color filter includes a lower substrate(110), a plurality of hemispheric shapes(120), an orientation film, and a cholesteric liquid crystal layer. The lower substrate is a transparent glass substrate. The hemispheric shapes are patterned on the lower substrate by using positive or negative photosensitive material. Diameters, heights, and arrangement of the hemispheric shapes are irregular to prevent a moire phenomenon or a color shift phenomenon due to light interference. The orientation film is formed on the hemispheric shapes. The cholesteric liquid crystal layer is formed on the orientation film.

Abstract: A high aperture and wide viewing single gap transflective LCD(Liquid Crystal Display) is provided to improve an aperture ratio by disposing secondary capacitance in a voltage-reflectance curve, thereby maximizing aperture ratios of the voltage-reflectance curve and a voltage-transmittance curve. One pixel is divided into a voltage-reflectance curve and a voltage-transmittance curve. A cell gap of the voltage-reflectance curve and the voltage-transmittance curve is almost equally formed. A reflectance plate(2) functioning as a counter electrode and plural transparent pixel electrodes(4) of slit and bar types are formed in upper end of the voltage-reflectance curve as leaving a space for a passivation layer(3). A fringe field is formed according as a vertical filed component and a horizontal field component coexist when voltage is applied. In the voltage-transmittance curve, a pixel electrode of a plate shape is formed in a lower array substrate(1). In an upper substrate(9), a transparent counter electrode(8) is formed in a location of the voltage-transmittance curve. By coating vertical alignment layers to both of the upper and lower substrates, LC is vertically erected before applying initial voltage. The LC has negative dielectric anisotropy.

Abstract: A controllable viewing angle patterned vertical alignment LCD(Liquid Crystal Display) is provided to divide the area of a panel into an area for displaying a predetermined screen and an area for controlling a viewing angle. A lower substrate uses a transparent glass substrate or a plastic substrate. The first pixel electrode(15) is patterned to an upper partial area of the lower substrate at a constant angle. The second pixel electrode(15') is patterned on the remnant areas of the lower substrate toward left and right or up and down directions. A vertical alignment layer is located at the upper portion of the first and second pixel electrodes. A liquid crystal layer is arrayed vertically on the upper portion of the vertical alignment layer and has a negative permittivity anisotropy. The first common electrode is patterned on the lower portion of an upper substrate and has an electrode with the same size of the first pixel electrode. The second common electrode is formed on the remnant lower portion of the upper substrate by a plane shape and not separated from the first common electrode. A vertical alignment layer is located at the upper portion of the first and second common electrodes. Two pair of transistors are driven by two signal lines(11,11').
