Plastic Liquid Crystal Display with Polarizers Integrated Inorganic Conducting and Alignment Layers

摘要

We investigated polarizer integrated conducting and alignment functions SiO_2/ ITO/SiO_2 films on polarizer films for the high transmittance and contrast ration of liquid crystal (LC) cell. SiO_2/ITO/SiO_2 films were directly deposited on polarizer films using r. f. magnetron sputtering system at room temperature, which are used as substrates for plastic liquid crystal displays. To align LC molecules, we exposure on SiO_2 film surfaces with low-energy ion beam. Transmittance of twisted nematic (TN) and electrically controlled birefringence (ECB) cell with SiO_2/ITO/SiO_2/polarizer was higher by 3%～5% than those of SiO_2/ITO/glass/polarizer in average visible wavelength.
