    摘要： The display device includes a light source that generates first light, a conversion layer that outputs a plurality of lights using the first light, and a color filter layer.
    The conversion layer includes first to third conversion layers, and the color filter layer includes first to third color filters. The first conversion layer and the second conversion layer may include the same material.
    The first conversion layer and the first color filter may convert the first dominant wavelength of the first light to output second light having a second frequency. The second dominant wavelength of the second light may be located at the first color vertex of the color reproduction rate standard.

    摘要： Disclosed is a reflecting screen configured to reflect an image introduced from a projector. The reflecting screen includes a black resin layer having a dark color, wherein the black resin layer includes a plurality of slopes formed at one surface thereof so as to face in a given direction, the slopes being arranged in the vertical direction, and stepped portions formed between the slopes, corrugations formed at the slopes, and a reflecting layer formed at the slopes of the black resin layer. The reflecting screen is capable of reducing raw material costs and manufacturing costs and reducing the weight and volume of a product, as a result of simplifying a multilayered structure of a reflecting screen.
