  • Patent number: 9405151
    Abstract: A display apparatus includes a display panel and a backlight unit. The display panel includes a first substrate and a second substrate. The first substrate includes a first base substrate and a wavelength transforming member. The wavelength transforming member is formed on a first surface of the first base substrate to change a wavelength of light to emit visible light having a predetermined wavelength. The second substrate includes a second base substrate and a light shutter member. The second base substrate faces the first base substrate. The light shutter member is formed on a first surface of the second base substrate facing the first surface of the first base substrate.

    Abstract: In a method for manufacturing a nanoparticle, a precursor (e.g., transition metal complex) mixed with polyethylene glycol (PEG) is thermally decomposed. A nanoparticle is formed from the thermal decomposition. PEG is cost effective and less toxic than chemicals that are conventionally used for nanoparticle production, so that costs for manufacturing the nanoparticle may be decreased. Further, PEG may be reused to produce more nanoparticles.
