    Abstract: An image sensor includes an optical sensor layer including a plurality of light-sensitive cells configured to sense light to generate electrical signals, and a color filter array layer disposed on the optical sensor layer and including a plurality of color filters respectively facing the plurality of light-sensitive cells. Each of the plurality of color filters includes a nanostructure in which a first material having a first refractive index and a second material having a second refractive index higher than the first refractive index are arranged. The first material and the second material are alternatively positioned at an interval less than a central wavelength of a color of the color filter. Thus, a thin image sensor having good wavelength selectivity and suitable for obtaining high resolution images is provided.

    Abstract: An illumination device includes a display panel including a first surface on which an image is displayed, a second surface opposite to the first surface, display pixels interposed between the first surface and the second surface, and a transmitting window interposed between the first surface and the second surface. The illumination device further includes a light source disposed on a side of the second surface of the display panel, and emitting light toward the second surface, and a light transmitter interposed between the light source and the display panel, and transmitting the emitted light to the transmitting window, the transmitted light being incident on the second surface of the display panel and being transmitted through the transmitting window toward the first surface of the display panel. The illumination device further includes a diffuser diffusing the light transmitted through the transmitting window.
