Electroluminescent device having electrical conductors arranged between adjacent display elements

摘要

In an electroluminescent display device having a plurality of display elements (12) each of which comprises a portion of a common organic electroluminescent (EL) layer (20) and first and second electrodes (18,22) on opposing sides of the EL layer, an electrical conductor (30) held at a predetermined potential is provided extending between the first electrodes (18) of adjacent display elements and in contact with the EL layer for sinking electrical current tending to flow laterally in the EL layer between the adjacent display elements. In an active matrix array device, the electrical conductors may be provided in the form of a grid extending around each display element pad electrode (18). In a passive matrix array device the electrical conductors may comprise conductor lines (50) extending between the address conductors (40) of one set.
