ABSTRACT:
In the manufacture of a color-display device comprising color-filter layers, phosphor haze may occur. Said phosphor haze adversely affects the picture quality. Phosphor haze can be reduced substantially, or precluded, by providing one, and only one, of the color-filter layers by means of a negative lithography process and, subsequently, providing the phosphor corresponding to this color-filter layer before the other phosphor layers.
