a substrate;
a thin film transistor forming layer on the substrate;
a wiring forming layer on the thin film transistor forming layer;
an LED mounting layer on the wiring forming layer;
a display portion mounted with an LED in the LED mounting layer:
a pixel circuit portion provided with a latch circuit for controlling the LED, the latch circuit provided in the thin film transistor forming layer; and
a shielding layer provided between the thin film transistor forming layer and the LED mounting layer,
wherein a fixed potential is applied to the shielding layer, and
the LED overlaps the latch circuit with the shielding layer therebetween.
2 . The display device according to claim 1 , wherein the fixed potential is a potential applied to an electrode of the LED.
3 . The display device according to claim 1 , wherein the shielding layer is provided over a first flattening layer covering the latch circuit.
4 . The display device according to claim 3 , wherein the LED is provided over a second flattening layer covering the shielding layer.
5 . The display device according to claim 3 , further comprising a conductive layer and an inorganic insulating layer between the first flattening layer and the shielding layer,
wherein the shielding layer overlaps the conductive layer with the inorganic insulating layer therebetween.
6 . The display device according to claim 1 , wherein the LED has a horizontal electrode structure.
7 . The display device according to claim 1 , wherein the LED has a vertical electrode structure.
