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 VA(vertically aligned) mode LCD using a polymer wall is provided to improve initial stability of a liquid crystal director in operating the LCD and reduce a response time by forming an inclined electric field from a cell upper substrate to a lower substrate. An upper substrate(2-a) is placed under an upper polarizer plate(1-a). A common electrode(3-a) is placed under the upper substrate, and is a transparent electrode from which an electrode of a diameter of 1 m, which causes an inclined electric field is removed at a central portion of a pixel in voltage application. A vertical alignment layer(4-a) is coated on a lower portion of the lower substrate, and makes initial alignment of liquid crystals perpendicular to the substrate. A polymer wall is formed at a lower substrate, maintains a cell thickness with the upper substrate, confines the liquid crystals, and determines initial orientation of the liquid crystals. A vertical alignment layer(4-b) makes initial alignment of the liquid crystal perpendicular to the substrate on the polymer wall and a surface of the lower substrate. A pixel electrode(3-b) is a transparent electrode placed under the polymer wall. The lower substrate(2-b) serves as a lower for the polymer wall, the vertical alignment layer, and the pixel electrode. A lower polarizer plate(1-b) is placed under a driving circuit, and is attached such that its transmission axis becomes orthogonal to the upper polarizer plate.
