PURPOSE: A luminescent display and a manufacturing method for the same are provided to customize a simple, inexpensive illuminated sign by an end user. CONSTITUTION: The luminescent display includes an organic light emitting layer(110) disposed between two electrodes. The organic light emitting layer(110) emits light upon application of a voltage across the anode and cathode. The anode and cathode inject charge carriers, i.e. holes and electrons, into the organic light emitting layer(110) where they recombine to form excited molecules or excitons which emit light when the molecules or excitons decay. The color of light emitted by the molecules depends on the energy difference between the excited state and the ground state of the molecules or excitons. The organic light emitting layer(110) typically has a thickness of about 50-500 nanometers, and the electrodes(120, 130) each typically have a thickness of about 100-1000 nanometers. |
