Abstract:
An electroluminescence display device, comprising:a plurality of display pixels arranged in a matrix within a display pixel region on a substrate, said display pixels having electroluminescence elements including an emissive layer between first and second electrodes; wherein within said display pixel region, power source lines for supplying power from a power source to said electroluminescence elements are disposed in a grid pattern extending in row and column directions of the matrix, wherein said power source lines include main power source lines arranged in plural numbers along the column direction of said matrix within said display pixel region, and at least one bypass power source line extended in the row direction of said matrix within said display pixel region to intersect and connect said main power lines, wherein said main power source lines and said bypass power source line are conductive lines separately formed in different processes, wherein said bypass power source line is formed in a layer located underneath said main power source lines and separated from said main power source lines by an insulating layer, and is connected to said main power source lines via contact holes.
