Abstract: The present invention relates to transflective color liquid crystal displays that provide for improved balancing and optimization of color and white points in transmissive and reflective mode. The invention is base on the deliberate increase of light absorbance at sub-pixels of selected colors.

Selecting the light absorbance in accordance with the present invention may be combined with the use of color filters having differentiated thickness and/or pinhole color filters.
