ABSTRACT:
A color display device is provided with a black-matrix layer, a phosphor pattern and color-filter layers. The theological behavior of the suspension and/or the evaporation of volatile constituents is influenced by the topology of the color-filter layers, with, in particular, projecting color-filter layers exerting an influence. As a result, variations in thickness between the phosphor layers occur. By reducing the differences in height between a projecting color-filter layer and the black-matrix layer, the variations in thickness between the phosphor layers are reduced and hence the quality of the picture displayed is improved.
