Abstract
A liquid crystal apparatus includes a scan line extending in a ±X direction, a data line extending in a ±Y direction that intersects with the ±X direction, a TFT having a semiconductor layer in which, at a position overlapping with the scan line in plan view, one source drain region and a channel region extend along the ±X direction, and at a position overlapping with the data line in plan view, another source drain region extends along the ±Y direction, and a first upper capacitance element and a second upper capacitance element provided at a position overlapping with the data line, so as to overlap with the other source drain region in plan view.
Claims12
An electro-optical device, comprising:
- a scan line extending along a first direction;
- a first data line including:
- a first body portion extending along a second direction that intersects with the first direction, and
- a first protrusion portion protruding from the first body portion along the first direction;
- a second data line adjacent to the first data line, the second data line including:
- a second body portion extending along the second direction, and
- a second protrusion portion protruding from the second body portion along the first direction;
- a transistor having a semiconductor layer which includes one source drain region at least partially overlapping with the scan line in plan view and electrically connected to the first protrusion portion of the first data line, a channel region at least partially overlapping with the scan line in plan view, and another source drain region at least partially overlapping with the second body portion of the second data line in plan view, and in which, at a position overlapping with the scan line in plan view, the one source drain region and the channel region extend along the first direction, and at a position overlapping with the second body portion of the second data line in plan view, the other source drain region extends along the second direction;
- and
- a capacitance element having a capacitance electrode provided, at a position overlapping with the second body portion of the second data line, so as to overlap with the other source drain region in plan view.
