A light emitting device having superior responsibility is provided. A pixel electrode (anode) connected to a drain wiring of an current control TFT has a slit. The slit becomes a path for light emitted from an EL layer, and emitted light can be extracted using a light shielding metallic film as the pixel electrode. A material having a low resistance can thus be used as the pixel electrode, and therefore a light emitting device having superior responsibility can be obtained.
