Abstract

One surface of a substrate of an LED module for a flat panel display has 8.times.8 element areas divided into a matrix form. Row electrodes extend on element areas arranged along the row direction, and column electrodes insulated from the row electrodes extend on element areas arranged in the column direction. At least one LED pellet is disposed for each element area and is connected to the row and column electrode associated with this area. A connecting pad is disposed as spaced apart from the four pellets in a unit area defined as a region consisting of four element areas. This connecting pad is connected to one of the row and column electrodes in the four element areas and is also connected through the substrate to a connecting pin arranged on the other surface of the substrate of the LED module.
