Abstract: 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 0null is 15% or less in area and a second component with an inclination angle value from 2null to 10null 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.

Abstract: In a semi-transmissive liquid crystal display device, the thickness of liquid crystal layer in the reflective region can be adjusted by controlling the film thickness of the organic insulating film for reflection and the film thickness of the color layer for reflection. Furthermore, the thickness of liquid crystal layer in the transmissive region can be adjusted by controlling the film thickness of the organic insulating film for transmission and the film thickness of the color layer for transmission. Since the thicknesses of liquid crystal layer in the reflective region and that in the transmissive region can be adjusted, the reflectance in the reflective region and the transmittance in the transmissive region can each be set at the most appropriate values.

Abstract: A TFT and a passivation film are formed on a transparent substrate and thereafter the passivation film is annealed. When measuring drain currents of a TFT at a fixed turn-on voltage (Von) and a fixed turn-off voltage (Voff), although performance of a TFT annealed (solid line) rarely changes, performance of a TFT not annealed (dashed line) changes to a large extent, in more detail, drain current drastically decreases in accordance with the change of TFT performance. This phenomenon means that on-resistance of a TFT not annealed is being increased to a great extent.

Abstract: 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.
