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.

A method for fabricating a system for displaying images including the TFT device is also disclosed.

System for displaying images including thin film transistor device and method for fabricating the same

An image display system has a multi-gate thin film transistor (TFT) disposed on a transparent substrate. The multi-gate TFT includes a silicon film layer, a first electrode and a reflecting layer. The silicon film layer is formed on the transparent substrate and has a first crystallization zone and a second crystallization zone, which are not adjacent to each other. A grain size of the first crystallization zone is smaller than a grain size of the second crystallization zone. The first electrode corresponding to the first crystallization zone is disposed on the silicon film layer. The reflecting layer corresponding to the second crystallization zone is disposed on the transparent substrate. The silicon film layer is disposed on the transparent substrate and the reflecting layer.
