Abstract:
An electrooptical panel comprising:a plurality of data lines;a plurality of scanning lines crossing at least one of the data lines;thin film transistors that electrically contact each data line, each thin film transistor comprising a semiconductor layer and a gate insulation film separating the semiconductor layer from a gate electrode;a plurality of pixel electrodes disposed in a matrix and that electrically contact a corresponding thin film transistor;at least one interlayer insulation film formed over the semiconductor layer and the gate electrode of each thin film transistor;contact holes formed in the at least one interlayer insulation film to allow electrical contact between each pixel electrode and a drain region of a corresponding thin film transistor; anda lift-up film formed under at least one contact hole, wherein the lift-up film is disposed below a connecting portion of the pixel electrodes and the drain region of the thin film transistor, protruding from the semiconductor layer below the scanning lines.
