A display device includes a display portion mounted with a first LED and a second LED are mounted, a pixel circuit portion provided with a first pixel-circuit thin film transistor electrically connected to the first LED and a second pixel-circuit thin film transistor electrically connected to the second LED, a drive circuit portion provided with a drive-circuit thin film transistor, and a shielding layer provided between the display portion and the drive circuit portion. A fixed potential is applied to the shielding layer. The second LED overlaps the drive circuit portion with the shielding layer therebetween.
