1. A light emitting diode (LED) display device comprising:
a pixel-driving circuit on a substrate;
a capacitor-integrated LED connected to the pixel-driving circuit; and
a black matrix between the capacitor-integrated LED and an adjacent capacitor-integrated LED,
wherein the capacitor-integrated LED has an active layer and a capacitor disposed under the active layer,
wherein the capacitor is overlapped with the active layer,
wherein the capacitor is configured as a storage capacitor for storing a data voltage,
wherein the capacitor of the capacitor-integrated LED comprises a first capacitor electrode, a second capacitor electrode, and a capacitor dielectric layer between the first capacitor electrode and the second capacitor electrode,
wherein the second capacitor electrode is closer to the active layer than the first capacitor electrode,
wherein the pixel-driving circuit comprises:
a switching thin-film transistor or a driving thin-film transistor connected to the first capacitor electrode, and
a switching thin-film transistor or a driving thin-film transistor connected to the second capacitor electrode, and
wherein the LED display device further comprises:
a first insulating layer between the switching thin-film transistor and the driving thin-film transistor;
a second insulating layer between the pixel-driving circuit and the capacitor-integrated LED; and
a third insulating layer between the capacitor-integrated LED and an adjacent capacitor-integrated LED.
