Abstract:
A color filtering member for improving the brightness of a display device is presented. The color filtering member includes colored regions (e.g., regions with RBG color filters) and black-and-white regions for transmitting white light. The black-and-white regions may be colorless gaps between adjacent colored regions. Multiple planarizing layers may be deposited on the colored regions and the black-and-white regions to form a surface that is sufficiently even. The color filtering member may include an intercepting region that extends between neighboring colored regions. The position of the intercepting region is not centered between the two colored regions that it separates. Rather, the intercepting region is shifted in the direction of rubbing (in the direction of liquid crystal alignment) to more effectively cover the regions where light leakage occurs. This color filtering member may be combined with an array member and a liquid crystal layer to form a display device.
