To provide a light emitting device high in reliability with a pixel portion having high definition with a large screen. According to a light emitting device of the present invention, on an insulator ( 24 ) provided between pixel electrodes, an auxiliary electrode ( 21 ) made of a metal film is formed, whereby a conductive layer ( 20 ) made of a transparent conductive film in contact with the auxiliary electrode can be made low in resistance and thin. Also, the auxiliary electrode ( 21 ) is used to achieve connection with an electrode on a lower layer, whereby the electrode can be led out with the transparent conductive film formed on an EL layer. Further, a protective film ( 32 ) made of a film containing hydrogen and a silicon nitride film which are laminated is formed, whereby high reliability can be achieved. |
