  • HYBRID-TYPE POLARIZER, METHOD OF MANUFACTURING THE SAME AND DISPLAY DEVICE HAVING THE SAME
    Publication number: 20100091217
    Abstract: In a hybrid-type polarizer having a reflective-type polarizing filter and a color filter, a method of manufacturing the hybrid-type polarizer and a display device having the hybrid-type polarizer, the hybrid-type polarizer includes a base member and a polarizing color filter member. The polarizing color filter member includes a plurality of metal gratings in a plurality of regions of the base member. The metal gratings in the regions have different sizes from each other. Each of the metal gratings transmits a first portion of an incident light and reflects a second portion of the incident light. The invention improves image display quality and lowers the manufacturing cost.
