Abstract

An electrowetting display device includes a first and a second transparent substrates, multiple partition walls, a polar liquid, a non-polar liquid, and a phosphor layer. The non-polar liquid is opaque and immiscible with the polar liquid. The phosphor layer is formed on at least one of the first and the second transparent substrates. The phosphor layer comprises a first part that transforms the short-wavelength light into red light, a second part that transforms the short-wavelength light into green light, and a third part that transforms the short-wavelength light into blue light or allows the short-wavelength light to pass therethrough without transformation. Each of the first, the second, and the third parts is corresponding to one pixel unit.
