PROBLEM TO BE SOLVED: To solve a problem of a display panel constructed by using single-crystal semiconductor thin-film light-emitting elements as pixels, that the greater the number of pixels of the display panel is, the higher the rejection rate of the display panel is due to crystal defects in the semiconductor thin film and defects, etc. in the manufacturing process.SOLUTION: A display panel is formed by using an LED array 12 comprising: an LED array substrate 57; a plurality of through vias 53, 54 formed with conductors at predetermined positions of the substrate penetrating it from the surface to the reverse side; an organic flattening film 58 formed on the surface; back electrodes 55, 56 formed on the reverse side and electrically connecting to the through vias; a plurality of single-crystal semiconductor thin-film LEDs 50 secured on a flattening layer; and wirings 61, 62 electrically connecting the electrodes of the single-crystal semiconductor thin-film LEDs 50 and the through vias 53, 54. In the LED array 12, all or part of the through vias are electrically connected to the electrodes of the corresponding single-crystal semiconductor thin-film LEDs 50, respectively. |
