Abstract
In an electro-optical device, a first transistor includes a first gate electrode electrically connected to a scanning line via a first contact hole in an insulating film. A second transistor includes a second gate electrode electrically connected to the scanning line via a second contact hold in the insulating film. A planar size of the first contact hole is different from a planar size of the second contact hole.
Claims10
An electro-optical device comprising:
- a scanning line provided between a substrate and an insulating film;
- a first pixel that includes a first transistor provided on a side of the insulating film opposite to the scanning line and the first pixel electrode electrically connected to the first transistor, in a display region;
- and
- a second pixel that includes a second transistor provided on a side of the insulating film opposite to the scanning line and the second pixel electrode electrically connected to the second transistor, in an area adjacent to the display region,
- wherein the first transistor includes a first gate electrode electrically connected to the scanning line via a first contact hole formed in the insulating film,
- the second transistor includes a second gate electrode that is electrically connected to the scanning line via a second contact hole formed in the insulating film, and
- a planar size of the first contact hole is different from a planar size of the second contact hole.
