    • An exemplary embodiment of an aluminum type plated steel sheet which excels in discoloration resistance, and weldability, which does not decorate after re-heating and which can prevent increasing of strength, and a heat shrink band using the same are provided. For example, the heat shrink band can be made of an aluminum type plated steel sheet consisting of a steel sheet being composed of, e.g., not more than about 0.005 mass % of C; not more than about 0.005 mass % of N; not less than about 0.1 mass % and not more than about 0.5 mass % of Si; not more than about 0.1 mass % of P; not more than about 0.02 mass % of S; not less than about 1.05 mass % and not more than 2.0 mass % of Mn; not more than 1.0 mass % of sol Al; a residual amount of Fe and inevitable impurities, and an aluminum type plated layer mainly consisting of Al being deposited thereon. Such exemplary sheet can be prevented from a discoloration upon, e.g., being re-heated at a temperature of not less than about 500° C. to not more than about 700° C.

    • An image display apparatus is disclosed which is capable of obtaining a projected image having high contrast. The image display apparatus includes a luminous flux dividing system dividing light from a light source into a plurality of luminous fluxes and a condensing optical system leading the luminous fluxes emerged from the luminous flux dividing system to a reflective liquid crystal display element. The condensing optical system includes a condenser lens, a field lens making light from the condenser lens substantially telecentric, a polarization beam splitter, and a ¼ phase plate disposed between the polarization beam splitter and the liquid crystal display element. In addition, the phase difference φ that the ¼ phase plate gives to the ray made incident into the ¼ phase plate at an angle θ satisfies: π/2×0.8
