Abstract:
1. An electro-optical device comprising: a data line and a scanning line that intersect with each other; a pixel electrode which is formed at a position corresponding to an intersection formed by the data line and the scanning line; an interlayer insulation film including a contact hole; and a transistor which includes a semiconductor film and a gate electrode, the semiconductor film being separated from the scanning line by the interlayer insulation film, the semiconductor film having a channel region, a data-line-side source/drain region that is electrically connected to the data line, a pixel-electrode-side source/drain region that is electrically connected to the pixel electrode, a first junction region that is formed between the channel region and the data-line-side source/drain region, and a second junction region that is formed between the channel region and the pixel-electrode-side source/drain region, the semiconductor film comprising a first partial region including the second junction region and a first connecting portion of the pixel-electrode-side source/drain region, the first connecting portion of the pixel-electrode-side source/drain region being electrically connected to the pixel electrode, the gate electrode being a greater distance from the scanning line than from the semiconductor film, the gate electrode overlapping the channel region, the gate electrode being electrically connected to the scanning line through the contact hole in the interlayer insulation film, the contact hole has a channel-region adjacent portion next to the channel region of the semiconductor film and has a first extending portion that extends from the channel-region adjacent portion along the first partial region of the semiconductor film when viewed in plan.
