This polarizing element is provided with a transparent substrate, an absorbing layer disposed on the transparent substrate and constituting grid-shaped convexities arrayed at a pitch smaller than the wavelengths in the optical bandwidth used, a dielectric layer formed on the absorbing layer, and a reflective layer formed on the dielectric layer. Because the absorbing layer, which interferes with and absorbs light, is in contact with the transparent substrate, heat dissipation can be improved and heat resistance of the polarizing plate can be improved.

Abstract: A diffusely reflective optical film includes a blended layer extending from a first to a second zone of the film. The blended layer includes first and second polymer materials separated into distinct first and second phases, respectively. The blended layer may have the same composition and thickness in the first and second zones, but different first and second diffusely reflective characteristics in the first and second zones, respectively. The difference between the first and second diffusely reflective characteristics may not be attributable to any difference in composition or thickness of the layer between the first and second zones. Instead, the difference between the first and second diffusely reflective characteristic may be attributable to a difference in birefringence of the first and/or second polymer materials between the first and second zones. The blend morphology of the blended layer may be substantially the same in the first and second zones.

Abstract: A liquid crystal display device includes: a liquid crystal layer which contains a liquid crystal composition; a pair of substrates opposed to each other across the liquid crystal layer; alignment layers placed on liquid crystal layer sides of the pair of substrates, respectively; and polarization plates placed on opposite sides from the liquid crystal layer sides, respectively.

A blue pixel, which is one of the pixels of different colors, is larger in area than any of the pixels of other colors. A loss of light in a short-wavelength range is thus reduced.
