Abstract: A transflective display device has a color filter portion for each pixel which includes portions of two different thicknesses. In one implementation, both thicknesses are used for the reflective part of the pixel, and the relative thicknesses as well as the proportion of different thickness layers can be controlled to enable independent control of the color filtering characteristics in the reflective and transmissive modes of operation. Another implementation uses different portions of light absorbing material for the functions of pixel definition and height adjustment, but these may be achieved with a single patterned layer.
