ABSTRACT:
A reflective type active matrix liquid crystal display device is provided which is capable of offering preferred images. The present invention provides a reflective type display device comprising an insulation substrate, a TFT array formed over the insulation substrate and having a plurality of pixel TFTs formed in a matrix form, at least one driver circuit formed over the substrate and having a plurality of driver TFTs to drive the TFT array, a reflective pixel electrode connected to the pixel TFTs and arranged above part or an entire of the driver circuit, and at least one power source interconnect connected to the driver circuit and formed between the reflective pixel electrode and one of a source electrode and a drain electrode of the driver TFTs. This power source interconnect serves to shield against electrical noise caused by the driver TFTs constituting the driver circuit.
