PROBLEM TO BE SOLVED: To provide a display device capable of being manufactured through a small number of process steps, thereby capable of achieving high yield.SOLUTION: In an LED display, first and second light emitting diodes (5, 6) which have different electrical connection polarities each other relative to first and second electrodes (2, 3) are arranged in a matrix form on a substrate (1) in a state where the first and second light emitting diodes (5, 6) are mingled at random while the polarities are not aligned. When a solution including a plurality of the light emitting diodes (5, 6) are coated on the substrate (1) and a voltage is applied between the first and second electrodes (2, 3), the light emitting diodes (5, 6) can be electrically connected to the first and second electrodes (2, 3). |
