ABSTRACT:
The inventors has been anticipated that there is no problem in employing electron gun deposition as a method of forming a metallic layer on the EL layer because the TFT is disposed below the ET layer in the active matrix light-emitting device. However, since the TFT is extremely sensitive to ionized evaporated particles, the secondary electron, the reflecting electron, and so on generated by the electron gun, little damage was observed on the EL layer, but significant damages were found on the TFT when electron gun deposition is employed. The invention provides an active matrix light-emitting device having superior TFT characteristics (ON current, OFF current, Vth, S-value, and so on), in which an organic compound layer and a metallic layer (cathode or anode) are formed by means of resistive heating having least influence to the TFT.
