ORGANIC LIGHT EMITTING ELEMENT AND IMAGE DISPLAY DEVICE

摘要

PURPOSE:To improve resolution in an image display device used as a display. CONSTITUTION:An electron transporting layer 4 consisting of an organic material and a positive hole transporting layer 3 are nipped between two vertical electrodes transmitting a visual light of a first transparent electrode (+) 2 and a second transparent electrode (-) 5, and a current is carried between the two (+)- and (-)-transparent electrodes 2, 5, whereby plural sets of light emitting cells which emit lights are constituted. The light emitting cells of the plural sets are successively laminated on a transparent base 1, and the light emitting spectra from the respective light emitting cells are superposed and used to provide an organic light emitting element.
