Abstract
The invention discloses an organic electroluminescent device includes a substrate. The substrate includes a first control area and a second control area, a polysilicon active layer disposed on the first control area, and a first conductivity type source/drain area disposed in the polysilicon active layer. A first dielectric layer is disposed on the polysilicon active layer serving as a first gate dielectric layer, a first gate and a second gate is disposed on the polysilicon active layer and the second control area, respectively, wherein the first gate and the first conductivity type source/drain area constitute a first conductivity type thin film transistor serving as a switch element. A second dielectric layer disposed on the first gate and the second gate serves as a second gate dielectric layer, a micro-crystal silicon active layer disposed over the second gate.
