Abstract:
1. A liquid crystal display unit comprising: liquid crystal elements; two substrates that sandwich the liquid crystal elements; and a backlight that sequentially emits light of a plurality of colors, wherein a picture element including: at least one pixel that serves as a reflective region, at least one pixel that serves as a transmissive region, and the liquid crystal elements disposed in the at least one pixel that serves as the transmissive region are so driven as to display color information corresponding to a color of the light emitted by the backlight; a light focusing element that focuses the light emitted by the backlight on the transmissive region; the light focusing element is a microlens array provided on the substrate located on a side of the backlight; wherein the at least one pixel that serves as the reflective region comprises three different pixels, each having one of red, green, and blue color filters, and the at least one pixel that serves as the transmissive region is a pixel comprising a transparent layer, the three different pixels, each having one of red, green, and blue color filters, are arranged side by side in a first direction, wherein said three different pixels with the red, green and blue color filters and the pixel having the transparent layer are separately addressable via first, second, third and fourth switching elements, respectively, the pixel comprising the transparent layer is arranged in a second direction with the pixel having only the red color filter, the second direction being perpendicular to the first direction, such that the three different pixels, each having one of red, green, and blue color filters and the pixel having the transparent layer together form a rectangle, and the microlens array is formed in such a way that constituent microlenses thereof each coincide with a center of the pixel having the transparent layer.
