Abstract: A method for manufacturing a liquid crystal device includes preparing a precursor solution comprising a monomer, a blue dye, a green dye, and a red dye dissolved in the monomer, and liquid crystal molecules; and polymerizing the monomer of the precursor solution to form a liquid crystal layer. The blue dye, the green dye, and the red dye reflect light of different wavelengths from each other. A black color is available in a single pixel when, based on total amount of the blue dye, the green dye, and the red dye, the blue dye is present in an amount ranging from about 25 wt % to about 30 wt %, the green dye is present in an amount ranging from about 40 wt % to about 50 wt %, and the red dye is present in an amount ranging from about 25 wt % to about 30 wt %.

Abstract: Provided is a display device. The display device includes a lower display element where a substrate, a first lower electrode, a liquid crystal part, and a second lower electrode are sequentially stacked, an upper display element stacked vertical to the lower display element, where a first upper electrode, a light emitting part, a second upper electrode, and a protective part are sequentially stacked, and a middle part configured to deliver a driving signal to the lower and upper display elements, between the lower and upper display elements.
