Abstract
The present invention provides an electrooptical panel and electronic appliances provided with the electrooptical panel, wherein production yield and a pixel aperture ratio are not decreased even when pixels are made fine in the electrooptical panel using an active matrix addressing method by TFT addressing. The foregoing problems can be solved by putting a plurality of communication lines into electrical contact with the TFT array substrate via contact holes, wherein a plurality of pixel electrodes addressed using a TFT by the data line and scanning line are provided. A lift-up film is formed under the contact holes formed through an interlayer insulation film to put the drain region of the TFT in electrical contact with the pixel electrode.
