Abstract

The method for producing a lithium-lanthanum-zirconium composite oxide powder comprises: a first step for preparing a lanthanum zirconate powder having an average particle size of 20 nm to 200 nm, a lanthanum compound, and a lithium compound, respectively; a second step for depositing the lanthanum compound and the lithium compound on the surface of the lanthanum zirconate powder to generate a precursor powder; a third step for obtaining a lithium-lanthanum-zirconium composite oxide powder by heating the precursor powder for from one second to 30 seconds at from 900°C to 1200°C with the precursor powder dispersed in a carrier gas, using a gas having an oxygen partial pressure of from more than 1.0×10-30 atm to 1.0 atm as the carrier gas; and a fourth step for recovering the lithium-lanthanum-zirconium composite oxide powder obtained in the third step. According to the present invention, it is possible to suppress the scattering of Li and obtain a small-particle-size LLZ powder having excellent storage stability.

Abstract

Embodiments of a display device are described. A display device includes a backlight unit having a light source and a liquid crystal display (LCD) module. The LCD module includes a nanostructure-based color conversion (NS-based CC) layer and a light extraction layer. The NS-based CC layer is configured to receive a primary light, from the light source, having a first peak wavelength and to convert a portion of the primary light to emit a first portion of a secondary light having a second peak wavelength. The second peak wavelength is different from the first peak wavelength. The light extraction layer is optically coupled to the NS-based CC layer and is configured to prevent total internal reflection of a second portion of the secondary light. The light extraction layer has patterned features with one or more dimension in nanometer scale.
