In addition, when a phosphor layer is applied to the front glass plate as in the past, it is excited by ultraviolet light from adjacent cells and color crosstalk occurs, but in the present invention, since the phosphor layer is close to the electrode, it is possible to create a barrier. This improves efficiency and almost eliminates crosstalk problems. Furthermore, since the protective film is formed on the phosphor layer, it is possible to prevent the phosphor layer from deteriorating due to sputtering.
