A color‐filterless backlight utilizing reflective and refractive element in the light guide plate for light extraction and color pixel separation has been integrated with polarization recycling scheme based on wire grid polarizer and quarter wave plate on reflector. All the functional elements modulate and direct light path in a predictable way and therefore can work together properly to improve the efficiency loss at color filter and down polarizer simultaneously.
