| Research Abstract |
To establish a design guide for realizing high brightness and polarization ratio in liquid crystal (LC) electrochemiluminescent (ECL) cells with an emissive layer of a nematic LC layer doped with an organic fluorescent dye, fundamental light-emission properties have been evaluated. It was found that the decrease in the work function of anode metals is effective on the increase in the brightness and the external quantum efficiency and the fluorescent dyes with high photoluminescence polarization ratio also exhibit high polarization ratio in the electrochemiluminescence. Furthermore, LC-ECL cells with a colgated emissive layer revealed polarization emission in the normal direction of the substrate surface.
