In the transparent/scattering state switching element, two transparent substrates are provided parallel to and separated from each other, and an electrode is provided to the surface of each transparent substrate. A scattering seal member is also provided between external peripheral portions of the transparent substrates, and a PDLC layer is enclosed in a space sealed by the scattering seal member between the transparent substrates.

摘要： A light source device which is uniform in the intensity of distribution of an emitted light and high in the optical utilization efficiency, a display device which is high in recognability and is energy-saving, and an information terminal are provided. A reflecting portion is formed on a surface opposed to an emitting surface of a linear light guide. The reflecting portion is periodically formed with a total reflecting surface guiding a light incident on a linear light guide from a point light source, a light extracting surface allowing the light to reflect in such a way as to emit the light guiding the linear light guide from the emitting surface, and a re-incidence plane which takes the light transmitted but not reflected on the light extracting surface into the linear light guide again. By changing the size of the light extracting surface and the re-incidence plane, the intensity of distribution of the emitting light from the linear light guide can be made uniform.

摘要： A method of displaying a color video picture according to a field sequential process is provided. A display device displays an image comprising a matrix of pixels. One frame image is composed of four field images ranging from a first field image to a fourth field image. With four adjacent pixels handled as one unit, the colors R, G, B, W of illuminating lights applied to the pixels in each unit are different from each other, and the arrangement of the colors is successively switched or changed in each field period. Information representing the colors R, G, B, W separated from a video signal is displayed sequentially in successive fields at positions corresponding to the colors of the illuminating lights applied to the pixels and times at which the illuminating lights are applied to the pixels.
