摘要： A reflector for a reflection-type LCD device is provided, which reflects efficiently incident light to the viewer's side and that suppresses the change of color tone. The reflector comprises a roughened surface having a protrusion pattern. The protrusion pattern gives inclination angle to the surface according to a specific distribution where a first component with an inclination angle value of 0° is 15% or less in area and a second component with an inclination angle value from 2° to 10° is 50% or greater in area. The protrusion pattern gives a variation range of chromaticity coordinates (x, y) on a chromaticity diagram dependent on an angle of view. The variation range is limited in a circle on the chromaticity diagram. The circle has a radius of approximately 0.05 and a center at a point corresponding to white color.

摘要： A reflective LCD device includes a reflective film having a convex and concave pattern, wherein the convex and concave pattern includes a plurality of pattern groups having a common pattern and each including a plurality of (N) figure elements. Each figure element is obtained by randomizing a corresponding figure element in a standard pattern including a plurality of standard figure elements. In the randomization, the discrete angle of bright spots generated by diffraction of the reflected incident light assumes 0.01 degrees or smaller. The discrete angle α of the bright spots is defined by: α=(λA/Ls×N)·(180/π) where λA and Ls are average wavelength of the incident light and pitch of the standard pattern, respectively.

摘要： A reflection electrode has an undulated shape and whose normal direction is distributed unevenly to a specific azimuth angle and whose reflection light intensity depends on said azimuth angle. Openings are formed in that area of the reflection electrode which has a tilt angle of 0 degree to 2 degrees and/or a tilt angle of 10 degrees or higher. The retardation of a liquid crystal layer is changed by making the liquid crystal molecular alignment mode different between the openings and the reflection electrode, so that the intensity of output light is increased in reflection mode as well as in transmission mode. The balance of colors displayed in transmission mode is determined by determining the area of the openings in pixels of each color, and the color temperature is set higher in transmission mode than in reflection mode. This provides a semi-transmission type liquid crystal display which has an excellent visibility in reflection mode as well as in transmission mode.

摘要： In a transflective type LCD provided with a transparent region and a reflection region in each pixel, when an irregular film 11 is formed on an active matrix substrate 12 to form irregularities of a reflection electrode film 6, the irregular film 11 is specifically formed to almost the same film thickness in both the transparent region and the reflection region to provide substantially the same inter-substrate gap in these two regions so that they may have almost the same V-T characteristics and also the reflection electrode film 6 made of Al/Mo is formed so as to overlap with a transmission electrode film 5 made of ITO all around an outer periphery of the transmission electrode film 5 by a width of at least 2 μm, thus suppressing electric erosion from occurring between the ITO and Al substances at the edge of the transmission electrode film 5.
