Abstract:
1. An electrowetting display device, comprising: a first transparent substrate and a second transparent substrate facing each other; a plurality of partition walls formed between the first and the second transparent substrates to divide the electrowetting display device into a plurality of pixel units; a polar liquid disposed in each pixel unit; a non-polar liquid disposed in each pixel unit, the non-polar liquid being opaque and immiscible with the polar liquid; and a phosphor layer formed on at least one of the first transparent substrate and the second transparent substrate and receiving short-wavelength light incident to the electrowetting display device, the phosphor layer comprising a first part that transforms the short-wavelength light into a first light, a second part that transforms the short-wavelength light into a second light, and a third part that transforms the short-wavelength light into a third light or allows the short-wavelength light to pass therethrough without transformation, wherein the first light, the second light and the third light are visible light and their respective wavelength bands are different from each other, and each of the first, the second, and the third parts corresponds to one pixel unit.
