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."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Nanostructure based display devices with improved light extraction efficiency","description":"Embodiments of a display device are described.
