Abstract: An input device which includes a light-transmissive touch panel, a phase difference plate disposed on the opposite side to an input operation surface of the touch panel, a ¼ wavelength plate disposed on the side of the input operation surface of the touch panel, and a polarizing plate on the touch panel side, which is disposed on the ¼ wavelength plate toward the input operation surface of the touch panel, wherein a ratio R1 (450 nm)/R1 (590 nm) of the phase difference value R1 (450 nm) for the phase difference plate at a wavelength of 450 nm to the phase difference value R1 (590 nm) for the phase difference plate at a wavelength of 590 nm is greater than a ratio R0 (450 nm)/R0 (590 nm) of the phase differences value R0 (450 nm) for the ¼ wavelength plate at a wavelength of 450 nm to the phase difference value R0 (590 nm) for the ¼ wavelength plate at a wavelength of 590 nm, the phase difference value R1 (590 nm) for the phase difference plate at a wavelength of 590 nm is smaller than the phase difference val

Abstract: The present invention provides a color transflective liquid crystal display that is capable of display with good coloring and high visibility in both a reflective mode and a transmissive mode while suppressing deterioration in color reproduction caused by unevenness of the spectral properties of the illumination light, if any. The liquid crystal display can include a liquid crystal display panel including pixels formed of a plurality of sub-pixels each corresponding to different colors, and an illumination device, wherein the liquid crystal display panel includes a transflective layer and a color filter of color corresponding to each of the sub-pixels.

Abstract: A TN liquid crystal 140 is used as a liquid crystal panel, and a polarizer 130 is provided above the TN liquid crystal 140 while a polarizer 135, a light scattering layer 150 and a polarized light splitter 160 are provided in this order under the TN liquid crystal 140. Furthermore, under the polarized light splitter 160, there is provided a light guide 190 for introducing light of a light source 191 from under the polarized light splitter 160 and a reflecting plate 200. The polarized light splitter 160 is a reflecting polarizer which can accomplish the effective utilization of light so that extremely bright reflective and transmissive displays are obtainable. Additionally, since a light diffusing layer 150 is provided, even if the distance from the TN liquid crystal 140 to the reflecting plate 200 is prolonged, in the reflective display, no double image nor display bleeding occurs.
