Abstract: A display apparatus includes a backlight unit which generates light and provides the light to a display panel which displays an image with the light, a first polarizer disposed on the backlight unit, a third polarizer disposed on the first polarizer, a second polarizer disposed between the first polarizer and the third polarizer, a light transmittance layer which blocks or transmits the light therethrough to display the image, disposed between the first polarizer and the second polarizer, and a color conversion layer disposed between the second polarizer and the third polarizer, and including a color conversion material which converts a color of light transmitted through the light transmittance layer and the second polarizer. A polarizing axis of the third polarizer is different from a polarizing axis of the second polarizer.

Abstract: A light source module includes a receiving container, a light source disposed in the receiving container and a filter filtering the light produced from the light source. A backlight unit includes a plurality of light source modules. The plurality of light source modules include a first light source module with a filter and a second light source module alternately disposed with the first light source module. The filter includes a substrate, a transparent layer disposed on the first metal layer and a second metal layer disposed on the transparent layer. The filter transilluminating light of specific area is disposed on the light source module. Thus, the backlight unit having high color reproducibility may be manufactured.

Abstract: A display apparatus includes a light source generating blue light. A display panel is configured to display an image. A light guide member is disposed below the display panel. A first light conversion layer is disposed between the light guide member and the display panel. The first light conversion layer includes a plurality of quantum dots. A low refractive layer is disposed between the light guide member and the first light conversion layer. The low refractive layer has a refractive index that is less than that of the light guide member. A second light conversion layer is disposed between the light source and the first light conversion layer and includes a plurality of fluoride-based or nitride-based phosphors. The first light conversion layer is configured to convert the blue light into green light, and the second light conversion layer is configured to convert the blue light into red light.
